MULSIM/BM: A Structural Analysis Computer Program for Mine Design

摘要

The report contains the final user's guide for the MULSIM/BM computer program which is an improved program using the boundary-element approach for geomechanical analysis of mine plans in single or multiple coal seams. The report presents the improved features of the MULSIM/BM program including ability to specify up to 26 material property sets, a new material model capability for gob and inserted materials such as packwalls or cribs, ability to model a large area with a grid of undivided blocks and to subdivide only a specified fine-mesh portion of these blocks into elements, and specification of extraction ratios for the undivided blocks. In addition, an interactive graphics mesh generator program was written to accompany MULSIM/BM. The report contains the user's guide and program listings.
