The Pit Slope Calculator allows one either to (i) calculate the IRA given a set of criteria (bench height, BFA, and catch bench); or (ii) calculate the catch bench width given the height, BFA, and IRA.
-
Single Bench Height (BH): is the input height of a single operating bench
-
No. of Benches between catch benches: is the input for single, double, or triple benching
-
Total Height (TH): is the calculated total height (# of benches X single bench height)
-
Bench Face Angle (BFA): is the input bench face angle, in degrees
-
Catch bench (CB): is the width of the catch bench, either as an input or a calculated value
-
Inter-Ramp Angle (IRA): is the slope angle in degrees, either as an input or calculated value
