Block Reserves

Report Block Reserves

Use the Block Reserves option to report reserves for polygons divided into fixed length blocks. These polygons usually represent pits, mining blocks or strips.


Instructions

On the Rsvute menu, point to Reserves, and then click Block Reserves to display the Block Reserves panel.

Block

Length

Enter the block length. The polygons are divided into blocks of this length. The orientation of the block is determined by the mining direction as indicated by the arrow displayed when a polygon is selected. Use the Tools > Direction option to change the mining direction.

Save Layer

Enter the name of the layer in which to save the block polygons. The saved polygons are written to the current design database.

Limits

Design DB

Enter, or select from the drop-down list, the name of the design database containing the limit polygons.

Layer

Enter the name of the layer that contains additional limit polygons. Wildcards are allowed.

Objects

Enter the name of the limit polygons. Wildcards are allowed. These limit polygons are used to apply an overall limit to the reserve area. It can be used to generate reserves for a given lease or property section.

Horizons

This section contains a list of horizons. Select the horizons to be reported. Standard windows selection methods apply, such as Shift + click to select adjacent horizons and Ctrl + click to select non-adjacent horizons. You can also right-click in the section and click Select all. Only the selected horizons are reported. Rsvute still acknowledges that the other horizons exist, and hence the burden values are not affected by this list. If no horizons are specified, then all known horizons are reported.

Variables

This section contains a list of variables. Select the variables to be reported, for example OB, MD, AS, SU etc. Standard windows selection methods apply, such as Shift + click to select adjacent variables and Ctrl + click to select non-adjacent variables. You can also right-click in the section and click Select all. Each variable corresponds to a grid. If the grid for a particular horizon/variable combination does not exist, a set of "...." will appear on the report instead of a value. If no variables are specified, then all known variables are reported.

Note:   If a variable does not appear in the list, it has not been defined in Grid Calc.

No Variables

Select this check box if you don't want variables to be reported.

Burden

Select this check box if you want Rsvute to derive the overburden and interburden values. Rsvute does this by comparing the surfaces that make up each horizon, checking for overlap and volumes between each pair. In addition to the volumes, stripping ratios are also reported.

Note:   Because of the cell by cell checks and calculations required, selecting this check box will considerably slow the Rsvute execution time. If burden values are required on a report, it is much faster to calculate OB and MD (overburden and midburden) grids and report on these directly.
