Observation History

Source file: modelling-observation-history.htm

The Observation History tool displays the history of vibration observations for a site.

To open and use the Observation History panel, follow these steps:

  1. On the Analysis ribbon, in the Modelling group, select Observation History. The main Observation History panel will appear.

  2. There are four filter types that you can apply to filter the data presented in this table. You can either apply a single or multiple filters at the same time. Clicking Filter when all filters are unchecked will cause all observations to be displayed.

    • Filter by monitoring station: You can select multiple stations from the drop-down menu and only observations from those stations will be displayed.

    • Filter by tag: When you enter text in the Tag field, the list will be filtered to only include observations that have a tag containing the entered text.

    • Filter by detonation location: This will display all observations with detonation coordinates within the specified filter radius of the provided location.

    • Filter by date: This will display only the observations that were recorded between the first and the last date you provide.

  3. To enter data, click the Add entry... button. This will open a new panel.

    In this new panel, specify the following fields:

    1. In the Monitoring section, select a monitoring station from the drop-down menu. This list features the locations for this site as defined in Locations (Home ribbon > Setup group > Site).

    2. Define at least one of either Vibration or Overpressure.

    3. In the Blast section, use one of the two methods to enter an observation result: From tie-up or Manual entry. Using the From tie-up option requires a valid tie-up object to be middle-mouse dragged from the explorer to the tie-up field. BlastLogic will then calculate the detonation coordinates, maximum instantaneous charge (MIC) and detonation time from this tie-up using a Timing window and Propagation rate that you input. The detonation coordinates are defined as the collar location of the closest hole to the monitoring station that contributed to the MIC.

    4. You can optionally enter a custom tag to help identify this vibration observation.

    5. Click OK to save the vibration observation and close the panel.

The main Observation History panel also allows you to perform the following operations:

  • Click Delete row to remove the selected observation from the table. This also removes the vibration observation from the BlastLogic server database.

  • Click Import from CSV... to load vibration observations from a CSV file.

  • Click Export table to CSV... to save the vibration observations that are currently filtered in the table to a CSV file.

  • You can edit the Vibration Observation table by double-clicking an editable cell. Any changes made can be saved by clicking Save changes.
