摘要

The safe, productive exploitation of coal in multiple-seam situations requires specific design technology. At present, there are two general design approaches that the mining engineer can use to analyze the multiple-seam problem in question: simple empirical relationships or complex numerical models. Often, the empirical approaches are too general for the specific problem, and the numerical models require too much time and expertise for the practicing engineer. In this paper, a new program is presented, designed for quickly and easily calculating the stresses, strains and safety factors associated with basic multiple-seam mining situations. The program implements a simplified, two-dimensional boundary-element method to model the complex multiple-seam stress and displacement interactions. The program incorporates automatic coal and gob property generation to simplify the input, and it inherently calculates pillar safety factors to enhance the output.
