Abstract
The Bureau of Mines has developed MULSIM/BM, an improved computer program using the boundary-element approach for geomechanical analysis of mine plans in single or multiple coal seams. This information circular presents the improved features of the MULSIM/BM program. The four major improvements are (1) ability to specify up to 26 material property sets, (2) a new material model capability for gob and inserted materials such as packwalls or cribs, (3) 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 (4) specification of extraction ratios for the undivided blocks. In addition, an interactive graphics mesh generator program was written to accompany MULSIM/BM. A complete user's guide and program listings are included. The MULSIM/BM and mesh generator programs are available on tape from the National Technical Information Service.
