Setting Up and Using Benches Options
The Default bench height, specified in meters, is used to determine the toe elevation of a bench according to the String Position as follows:
-
Crest: Toe RL = String RL – Bench Ht
-
Mid-Bench: Toe RL = String RL – (Bench Ht/2)
-
Toe: Toe RL = String RL
If DPLUS and DMINUS are used then:
Bench ht = (DPLUS + DMINUS)/2
If you choose to perform an automatic search for bench exits, the Vertical search tolerance is considered relative to the toe reference level and is plus or minus. |
The Vertical search tolerance, for the String Position options shown on the Select Data panel, using a default bench height, can be illustrated as follows:
Using a variable bench height (DPLUS and DMINUS option) can be illustrated as follows:
