摘要
结合FLAC3D数值模拟软件,对杨庄煤矿3642采面Ⅲ64采区充填开采过程进行模拟分析,得出充填开采中充填体起到了支撑覆岩和为煤柱提供侧限的保护作用,从而很大程度上减小因煤层开采对地面建筑物的影响。
Combining with the 11164 Mining Area of 3642 Mining face of Yangzhuang Coal Mine, the paper undertakes the simulation analysis of the backfill and mining process with the numeric simulation software, FLAC3D and concludes the filler can support the overlying strata in the backfill mining process and provide lateral restraint protection for the coal columns, so as to reduce the influence of the mining at the strata on the buildings on the ground maximally.
