The Bench Mining System: Progress in Two-Dimensional Simulation of Steering Characteristics

摘要

Computer programs which simulate the vertical steering characteristics of the thick seam bench mining system were adjusted, in order to eliminate unwanted penetration of the floor. A flow chart which describes program functions needed to obtain bench fit is presented. Results for a variety of floor profiles confirm the validity of the fitting routines, so these routines were incorporated into color graphics simulation programs. Effects of interaction between roof support and bench can be incorporated into the simulation routine. Roof support and roof beam fitting routines work well for chocks with a very short front extension, but less well for long based chocks.
