Stability monitoring window

You use this window to analyse stability monitoring data by both graphical and analytical means to aid in the investigation of pit wall stability and the prediction of failure of pit walls.

To run this function: Choose File > Open > Stability monitoring window, or View > Other windows > Stability monitoring window, or Survey > Survey database > Stability monitoring,or...

  • In the Function Chooser, type STABILITY MONITORING, and press ENTER.

Central to the Stability Monitoring module is the Prism table in the Survey database. This table is an optional table in the Survey database and can be created at any time as need dictates. The Prism table permits the recording of multiple measurements to one or more monitoring locations, referred to as Prisms, over time.

These measurements will typically be recorded using an electronic theodolite/data recorder combination and stored directly into the table at the time of processing the data. Alternatively, observations may be manually entered into the Prism table when measured by different means such as level traverses or distance measurements between monitoring pins.

After entry of the monitoring prism data into the Prism table, data for one or more monitoring prisms may be selected for investigation graphically to examine the displacement, velocity and acceleration of the selected prisms. Appropriately labelled line graphs may be drawn for this purpose.

Detail and summary reports for printing may also be produced to permit a more analytical approach to the analysis of the results. These reports contain the numeric values of the displacements, velocities, and accelerations of each of these selected prisms.

Hard copy output of the graphs may be obtained via the GIF DUMP STABILITY or POSTSCRIPT DUMP STABILITY functions or by using the PRISMS TO STRINGS function to create a string file of the axes and line graphs for plotting via the PLOTTING module.
