摘要
为解决伏岩煤业武甲变电所下3203工作面安全经济开采问题,采用FLAC^3D数值模拟软件对五种限厚开采方案进行模拟。通过模拟,分析不同采厚及留设煤柱尺寸对地表沉陷的影响,为最终确定限厚开采方案提供依据。
In order to solve the problem of safe and economic mining of 3203 working face under Wujia Substation of Fuyan Coal Industry of Yangcheng Yangtai Group, Shanxi Province, FLAC^3D numerical simulation software was used to simulate five kinds of mining schemes with limited thickness. Through simulation, the influence of different mining thickness and size of coal pillar on surface subsidence was analyzed, so as to provide a basis for the final determination of mining plan with limited thickness.
