摘要
针对大同塔山煤矿石炭二叠纪特厚(9.8 m～29.21 m)煤层复杂地质条件,运用矿压理论分析和现场矿压观测的方法对综放开采工作面覆岩运动规律进行分析研究。通过对两种方法所得工作面初次来压和周期来压等结果的对比,分析得出存在差异的原因。
In view of the complex geological conditions of Datong Tashan Carboniferous-Permian extremely thick（9.8 m^29.21 m） coal seam,use of mine pressure theoretical analysis and field observation method,the fully mechanized sublevel caving mining face movement of overlying rock were analyzed.Analysis of reasons for the differences by comparing two methods that obtained initial and periodical pressure at the working face and other results.It provided the reference for the safe production in the working face.
