PIT SLOPE EXAMPLE PROBLEM:

Current Pit Slope is at DIP 45 , DIP DIRECTION 135.

1) Notice the influence of Weighting (bias correction) on the relative
   importance of the different discontinuity sets in CONTOUR PLOT.

2) Investigate the following failure modes and evaluate stability:

3) For expansion and deepening, what is the safest overall pit angle ?

    Toppling (sheet and column)
    Sliding Wedge Failure
    Planar sliding
    Slippage on local shears (TRACK DATA -> TYPE -> POLE PLOT)

4) Note that discrete features which may cause local problems (shears, etc)
   may not always show up on contour plots. Use TRACK-DATA ->TYPE ->POLE PLOT

5) What problems are to be expected on local bench slopes which will
   be steeper than this angle and what steps are needed to insure the
   integrity of roadways ?

6) What friction angle is required to achieve limit stability of slabs
   and wedges (Use LOCATE POLES -> DRAW CONE( F6 ))

6) What is the safety margin against toppling on a large scale. Is there
   a sufficient stability margin for earthquake prone areas?

7) Use SET-WINDOWS, TRACK DATA and LIST/HISTO->HISTOGRAM to investigate
   the representative spacings and persistance(length) of the structure.

8) What is the probability of failure (kinematic and fricitional stability) of
   planes for different pit strike and dip.
   (Use SET WINDOWS -> CONF/VAR ( ALT F9 )for variability limits
    Use LOCATE POLES -> DAYLIGHT ENVELOPE (ALT F6) for kinematics
    Use LOCATE POLES -> DRAW CONE for friction cone.)
