摘要
针对近距离煤层群开采条件下的某矿6207N工作面和5105N工作面进行了理论分析并结合数值模拟和现场矿压监测结果,研究此类条件下的下煤开采时的覆岩运动规律,对近距离煤层群下煤开采的矿压控制工作具有指导和借鉴意义。
The 6207N and 5105N working faces of a mine are analyzed according to theoretical analysis, numerical simulation and strata-pressure monitoring, the overburden strata movement behavior when the lower layer mining are researched, which can offer kind of guidance and reference on the strata-pressure controlling on the lower layer mining of the near-neighbored coal seams.
