摘　　要：随着矿山开采活动的进行,开采深度日益加深,开采环境日趋恶化,由此带来的安全生产问题亟待解决。根据峻德煤矿9103工作面工程地质情况,通过理论定量分析采场老顶初次来压及老顶周期来压期间其覆岩运动规律,利用数值模拟研究分析支承压力影响范围,从而得出大面积留设煤柱会对下部煤层开采造成恶劣影响的结论。With the development of mining activities, the mining depth increases gradually, and the mining conditions are getting worse. There are various safety problems which need to be addressed. According to the engineering geology in 9103 working face of Junde coal mine, the first weighting of main roof was quantificationally analyzed by theory, as well as the movement rule of overlying strata during the pe- riodic weighting of main roof. And the influence scope of bearing pressure was studied and analyzed by numerical sim- ulation. As a result, the conclusion was obtained that a large area of coal pillars had severe influence on the mining of un-derlying seam.
