Configuring the viewer

The viewer can be customised to show or hide different features. By default, the viewer displays a world map (Bing Maps), localised imagery (Cesium ion ), zones, stockpiles, and grade control blocks. In addition to this, you can control which details are displayed in the view.

When you first open the viewer page, the terrain is shown from a plan-view perspective. Depending on your settings, the following features may be displayed:

• Assets (localised imagery, for display in Cesium ion)

• Zones (or specific zone categories)

• Stockpiles (and specific features)

• The world map (using Bing Maps)

• Custom terrain (such as terrain scans)

To configure what you enable or see in the viewer, click to open the Options pane. These options are as follows:

• Viewer Assets: This section is where you select to enable your local imagery. Click the button to expand the section and use the checkbox to select available assets. Users can also add additional assets and topographical data (from the Cesium ion server), following these steps:

Using the viewer

The basic purpose of the viewer is to display topographical imagery, zones, stockpiles, and grade control blocks. As run-of-mine activities occur, the stockpiles form and change as material is added or removed. The viewer’s tools allow you to obtain and modify information relating to stockpiles and grade control blocks. These are described in the following topics.

Viewing content in the details pane

There are two ways that you can open the details pane: click on a stockpile, or right-click on a stockpile and select View details.

The details pane consists of the following:

• A stockpile overview with the following information:

  • Stockpile Name: Displays the stockpile name. You can edit the name. Simply click on the text to enable the mini editor, type in your new name, and click on to save it or to cancel.

    Tip:  Alternatively, right-click on the stockpile and select Rename from the context menu, then enter the new name into the New Stockpile name dialog box and click .

  • Parent Zone: The zone where the stockpile is located (by its centre position).
  • Area: The total area of the stockpile calculated by MaterialMRT.
  • Volume: The total volume of the stockpile calculated by MaterialMRT.
  • Mass: The total mass of the stockpile calculated by MaterialMRT.
  • Centre Position: The coordinates of the centre area of the stockpile.
  • Status (optional): Used as a flag to indicate an arbitrary condition such as surveyed, empty, building, etc.
  • Boundary behaviour: Indicates whether the boundary is dynamic Dynamic boundaries follow the outlying shape of the stockpile. As material is added or removed, the stockpile shape may change. In such cases, the boundary shape is updated. or static A static boundary does not change shape. Material added or removed are constrained to this boundary..

• The Material property list: Any properties associated with the stockpile are shown here. The material properties list also allows you to do the following:

  • Use the mouse wheel or scroll bar to view off-screen items.

  • Hover over a property with your mouse pointer to display pop-up statistics. Grade control and other numerical properties are shown as tonnage v grade histograms and text properties are typically shown as pie charts.

    Note:  Clicking on a non-stockpile zone such as a waste dump does not automatically load a material property list but you can generate one by clicking on the button.

    Tip:  To close the stockpile details pane, click at the top right-hand side of the details pane, or click outside of a stockpile or zone boundary.

Using the details pane tools

Four tools allow you to interact directly with a selected stockpile, they are: Merge stockpile, Adjust volume, Transform to bench, and Clear stockpile. To access any of these tools, use either of the following approaches:

• Click on the button at the top of the details pane.

• Right click on a stockpile to open its context-sensitive menu.

Merging Stockpiles

Merging allows two adjacent stockpiles to be combined into a single area, the stockpile boundary follows the extents of the combined stockpile model. To merge a stockpile with another, do the following:

1. Select the stockpile you want to merge using either mouse button If you left-click on the stockpile, use the ellipsis on the information pane. If you right-click on the stockpile, select Adjust stockpile from the context menu.

   Note:  The first stockpile you choose in this sequence will assert its name to the overall merger. The second stockpile name is overwritten.

2. Select , then click on the stockpile to be merged; a confirmation box opens.

3. To complete the merge, click the button. When the success confirmation appears, click to close it. The stockpiles are combined and the boundary is updated.

Adjusting the stockpile volume

The volume of a stockpile can be adjusted immediately, or at a specific time. For example, a surveyor determines the actual volume and later submits an update for correction. The operator then uses this data to update MaterialMRT.

To adjust the stockpile volume. do the following:

1. Select the stockpile you want to adjust using either mouse button If you left-click on the stockpile, use the ellipsis on the information pane. If you right-click on the stockpile, select Adjust stockpile from the context menu.
2. Click ; the Adjust stockpile volume dialog opens.
3. In the New Volume(unit³) The unit of volume inside the parenthesis are based on the unit of measure set in Preferences. field, the current volume is displayed. Enter the new volume in this field.
4. Choose when the change takes effect by selecting one of either radio button:
   • Select Now for the change to take effect immediately.
   • Select In the past and enter the date and time directly into the As of field. Alternatively, use the calendar picker () .
5. Click the button to complete the task, or to not proceed.

Transforming a stockpile to a bench

Material that is dumped using the MaterialMRT modelling algorithm produces structures that are conical and follow the predicted behaviour of material when settling. In reality, stockpiles are shaped by earthmoving equipment that typically form ramps and benches at the top of the stockpile that are surrounded by bunds. This tool models the stockpile to include these features.

The estimated height of the bench depends on determining the average height of the stockpile mass and its area The cross-section tool is a useful way of estimating what your bench height should be. —while the bund height is determined by site operator. If the bench height is set too high, little to no effect may occur and you will need to repeat the process. If the bench height is set too low, the stockpile may become overly flattened and force the surface area at the base of the stockpile to increase.

To use the transform to bench tool, follow these steps:

1. Select the stockpile to transform to a bench using either mouse button If you left-click on the stockpile, use the ellipsis on the information pane. If you right-click on the stockpile, select Adjust stockpile from the context menu.

2. Click , the Transform Stockpile Options dialog opens.

3. Enter the bench height and maximum bund height into their corresponding fields.

4. Click the button to complete the task, or to not proceed.

Clearing a stockpile

When a stockpile is cleared, any material properties are also removed. If the action occurs at a time in the past, MaterialMRT rewinds the system to that point in time and replays events that exclude the removed stockpile.

To clear a stockpile, do the following:

1. Select the stockpile you want to clear using either mouse button If you left-click on the stockpile, use the ellipsis on the information pane. If you right-click on the stockpile, select Adjust stockpile from the context menu.
2. Click ; the Clear stockpile dialog opens.
3. Choose when the change takes effect by selecting one of either radio buttons:
   • Select Now for the change to take effect immediately.
   • Select In the past and enter the date and time directly into the As of field. Alternatively, use the calendar picker ().
4. Click the button to complete the task, or to not proceed.

Viewer application buttons

The viewer application buttons are a group of separate tools located along the top of the viewer. They allow you to perform various actions, as follows:

	Create a cross section to view and examine the details of the stockpile. To learn more, see Making a stockpile cross section.
	Split stockpiles using a polygon to create your demarcation. To learn more, see Splitting a stockpile.
	Create a polygon over an area of interest to discover details about the underlying area. You can also Reclaim Reclaim is a tool that's available in the details pane after you select an area. an amount of mass, Edit Properties Edit properties is available in the details pane after you select an area. within the selected area or Clear Material Clear Material appears if the Select Area polygon is created over a stockpiled area. within that selection. To learn more, see Using the select area tool.
	Use this tool to transfer material from one location to another. To learn more, see Moving material in a stockpile to another location.
	Choose the preferred stockpile colour scheme. Select from Coloured by Height The colour scheme denotes the hieght of the stockpile model., Vertical Column The weighted average of the selected metric is applied to all the vertically stacked cuboid stacks in the stockpile., and Stockpile The stockpile mass of the entire stockpile or a selected property in the stockpile.. When Vertical Column or Stockpile is selected, open the Metric drop-down to choose one. The preferred colour scheme legend is shown at the bottom-right of the viewer, and all stockpiles are coloured accordingly.
	Recentre the view: Click the button to reorient the bearing of the terrain to its default and the tilt to plan view.
	Zoom To opens a list containing all zones inside the terrain map. You can do any of the following: Click on a location in the list to centre it in the viewer. Click Save to set the currently chosen location as the default. Click to centre the default location in the viewer. Search for a zone in the list by entering the keyword in the Search zone by name search bar.

Using the cross section tool

Cross Section allows you to create a section (P1 - P2) across any area containing stockpiles. The cross section produces an elevation of your stockpile that you can examine in detail. To create a cross section, follow these steps:

1. Click , the prompt Click where the cross section should start appears at the top of the viewer.
2. Position the stockpile near the centre of screen. If necessary, use your zoom to control your field of view over the stockpile.
3. Move your mouse to the required start position (P1) and right-click to anchor that point.
4. Move your mouse to where the cross section should finish (P2) and right-click to set your cross section. A graph of Height versus distance from P1is displayed inside the viewer. Each plot represents the highest cuboid in the stack.

Note:  You can drag the Points P1 ,P2, or C to adjust the path of the cross section as required. Dragging the centreline (C), moves the entire cross section line without changing its orientation. To examine the cross section in more detail, click the button. This opens a new browser page that allows you to view the cross section in more detail. To learn more, see Exploring a cross section.

Exploring a cross section

To view the cross section in detail, click the button inside Height versus Distance from P1 graph, this opens a new browser page called Cross-Section. The cross section page is divided into three sections: the Graphing type options, the viewer pane and a larger Height versus Distance from P1 graph.

Configuring the graphing type controls

Graphing type controls how your block form data is displayed. Select either of the following:

• Raw: The Cuboid Length and Width parameter setting in the Application bar’s Site Parameters .
• Averaged uses unit The SI or Imperial unit of length set in the Preferences page. blocks that are averaged and combined into a single block. To set the block size enter the value in the Resolution field.

Tooltip properties

You can control the amount of details that are included in the tooltips when hovering the mouse over a cuboid. Select either of the following:

• Show all: When selected, an overview of the cuboid (Distance from P1, height, width, and mass), and a list of the material properties statistics are displayed.

• Show selected: When selected, the following items are displayed:

  • Distance from P1: This is the horizontal distance of the cuboid from P1

  • Height: If the Graphing type is to Raw, the cuboid height applies. If Graphing type is Averaged, the height of the block is set by Resolution.

  • Width: If Graphing type is Raw, the cuboid width applies. If Graphing type is Averaged, the width of the block is set by Resolution

  • Value: The value of the averaged material property in a block. When viewing a text property, this is the percentage of the 'Highest Component

  • Highest Component A text property is made of components. These components are subproperties of the parent material property.: This is the dominant component. This heading only appears in text properties.

  • Components: When using averaged graphing, any material properties and their proportions are listed.

    Example

    In this example, setting Resolution to 3 causes a 3 x 3 m block to include the components lid5b (71.1%), lid6 (11.1%), and pg3u2 (17.8%)

    

Adjusting the cross section in the viewer

If required, you can continue to make adjustments to section P1 - P2, and C by dragging any of its anchor points. The graph profile plots are updated to reflect the new cross section.

Selecting a metric

A metric is a particular property in the stockpile. Refer to Material Properties Schema in User and System Management > Site Configuration Options > Material Properties. Select an available property from the Colour by metric drop-down. The graph is updated to reflect the selected colour scheme.

Structure of the cross section graph

The shape of the cross section models the deposition of material by location and the attributes of the materials which are set in the Cuboid Stack Modeller Settings in User and System Management > Site Configuration Options > Site Parameters.

The graph is represented in two basic ways, being:

• A profile that follows the height of the stockpile over the cross section. Each point in the profile represents the height of the sample distance from P1.

• The cuboid blocks representing the chosen metric by their properties (see above topic Selecting a metric) and composition. A cuboid is a block with a set width which is defined in Global Settings in User and System Management > Site Configuration Options > Site Parameters. The cuboid height directly relates to the metric property value, such as percentage, tonnage, TipStatus, etc.

Profile graph of the stockpile subdivision through the line P1-P2.

Cuboid block graph with the seam text property selected.

Viewing tooltip information

Information is contained within each cuboid block or plot on the graph. Simply hover your mouse pointer over an individual block or plot. The plot or cuboid block is highlighted and an information tooltip appears. In the case of a plot, this the distance from P1 and Height. If a cuboid is selected, its properties are displayed. The contents of the tooltip depend on the Tooltip properties setting.

Blocks that are stacked above others are representative of subsequent dumps of materials into that stockpile.

Splitting a stockpile

Stockpiles change with the movement of material. In some cases, it may be practical to separate an existing stockpile into two separate stockpiles. The Split Stockpile tool allows you to select the area to split and then allocate a name for the new stockpile. The process is as follows:

1. Manipulate the view so that the area to be split is easily seen.

   See also:   View manipulation (panning, rotating and zooming) in Getting Started > Viewer controls.

2. Click the button to start the tool. The prompt Click to add new points Press Space to finish appears and the mouse pointer changes to a cross.

3. Create a polygon around the area that you want to separate from the current stockpile boundary.

   See also:   Making polygons to create an area or zone in Getting Started > Viewer Controls.

4. When the perimeter is set, press Space to exit editing mode. When the Enter name for the new stockpile dialog appears. Enter the new name in the Name field and click the button. The stockpile boundaries are updated as shown below.

Using the Select Area tool

The Select Area tool allows you to create one or more polygons in your view. By creating an area, you can review information relating to this particular area. Additionally, two other functions appear in the details pane. They are Reclaim and Edit Properties.

How to select an area

1. Manipulate the view so that the area to be split is easily seen.

   See also:   View manipulation (panning, rotating and zooming).in Getting Started > Viewer controls.

2. Click to start the tool, the prompt Click to add new points, Press space to finish appears and the mouse pointer changes to a cross.

3. Create a polygon around the area that you want to see the details for.

   See also:   Making polygons to create an area or zone in Getting Started > Viewer Controls.

4. Press Space to complete the polygon, the details pane opens, displaying its polygon colour, mass, reclaim and edit properties hyperlinks (acting as buttons), and the remove polygon button () in a single row. If more polygons are added using the button, they are added to the list, as shown in the image below.

   Note:  Use the button to create your first polygon, then use the button to make additional polygons following the previous steps in this section.

   

   Tip:  If the details pane is closed, click on any polygon to open it again.

   Tip

   The Properties list below your polygons list contains statistical information for the present properties.

   Hover over a property to reveal that property’s statistics.

   

Reclaiming materials

Reclaiming is the process of adjusting material quantities from a stockpile (selected area) so that material is allocated to the appropriate sink, such as a crusher. To initiate a reclaim of material, do the following:

1. Click on Reclaim. The Reclaim Options panel opens.

2. In the Date Range field, use the calendar picker () to select a date or period of time, then click .

3. In Mass to Reclaim, enter the value to be reclaimed. If you are reclaiming the entire mass, retain the current maximum value.

4. In Mass per Load, enter the tonnage to be extracted per trip, based on the truck’s capacity.

5. In Digger Name, enter the name of the digger.

6. In Truck Name, enter the name of the truck.

7. Click to expand the Destination drop-down and make your selection.

   Tip:  To exit Reclaim Options at any time, click on the button.

8. Click , the Customise Reclaim Trips panel opens. A table listing the trips required are shown. You can refine the same parameters used in Reclaim Options for individual trips, including different destinations. To accept your settings, click . Otherwise, click to return to the Reclaim Options dialog or click to not proceed.

Editing selected area properties

Adjustments can be made to a high level of detail using the Edit Properties tool. In the Properties editor, you can do the following:

• Substitute a listed property using the drop-down (), next to that property.

• Change a value of a selected property.

• Delete a property.

• Add a new property, if available.

Adding Properties to your area selection

Properties can only be added if they are included in the Material Properties Schema. Refer to the above Note:

1. Click , a new item line is added to the property list with the next available property being listed.

2. Expand the drop-down to choose the property. Properties that are already added are greyed out.

3. In its Value field, type in a valid value.

4. Repeat the above steps until all the required properties have been included. Click when all properties have been added.

   Changes are updated to underlying resources in the area set by your polygons.

Altering and deleting properties

The properties editor panel allows you to modify properties that are currently listed. The following functions are available:

• Substitute a property in the list with another by clicking its drop-down and selecting an alternate property.

• Apply a value to a property by typing the new value into its Value field.

• Delete a property from the list by clicking .

Moving material in a stockpile to another location

The movement of material within MaterialMRT allows you to apply a simulated real-world correction to FMS based information by relocating the required amount of material to the correct location.

In some cases, disparity between competing sources of data may occur, for example, if unregistered trips or rehandles are performed. In such cases, these materials can be moved from a location within a stockpile or grade control block and moved to other location, such as a crusher.

To move material, follow these steps:

1. Adjust your view to identify the source location of the material.

2. Click , the mouse pointer changes to a cross.

   Note

   Additional help prompts are shown at the top of the viewer pane as shown below.

   

3. Click on the point where to move material from. A yellow line connects the selected location to the mouse pointer.

4. Click on the location where the material is to be moved to. The Movement Options dialog opens.

5. Confirm that the information is correct in the following fields:

   • Load location.

   • The Load Time. If necessary, adjust the time using the calendar picker ().

   • The Dump Location.

   • The Dump Time. If necessary, adjust the time using the calendar picker ().

   • The Payload mass. Adjust this value as needed

   • The Digger Name.

   • The Truck Name.

     Make the necessary corrections then click . The material is moved and MaterialMRT updates the data relating to the stockpile attributes and related data (but not the FMS source itself).

     Note:  When the movement transaction is complete, the material is removed from the model (stockpile or grade control block) and sent to its destination. If material is sent to a non-sink zone, the material is modelled and displayed at that location. Material sent to a sink, such as a crusher, is not displayed.
