摘　　要：借助弹塑性力学对综采工作面超前支撑压力显现及顶板运动规律进行了分析,在此基础上,采用动态方法对某矿近距离煤层下层煤开采时综采工作面的合理停采线位置进行了研究。结果表明:合理煤柱动态宽度应为79.32～82.38 m;研究成果为工作面的正常搬迁及采掘接替提供了保障,产生了一定的经济效益。The advanced supporting pressure and roof movement of in fully mechanized mining face were analyzed by elastic-plastic mechanics.Based on this,the rational end-mining line of fully mechanized mining face when the lower coal of close-distance coal seams was being mined was determined by dynamic method.The result showed that the reasonable dynamic width of coal pillar is 79.32~82.38 m.This provided safeguard to the normal removal of working face,and mining and excavation succession,having resulted in certain economic benefits.
