以现场实测的手段,运用围岩移动的基本规律,对阳泉荫营煤矿近水平15~#煤层8316预采顶分层滑移顶梁支架放顶煤工作面顶煤的移动变形规律进行了分析和研究,阐述了顶煤放落前所经历的三次破坏过程以及支承压力、回采工序、支架支撑对顶煤的破坏作用。
Based on the field test and the basic law of surrounding rock movement, the movement and deformation of top coal in the top coal caving face of 8316 pre-mining tiered slip top beam support in Yangquan Yinying Mine is analyzed And the study elaborated the three destruction processes that the jacking coal experienced before falling and the destructive effects of the supporting pressure, the mining process and the support on the top coal.
