摘要
为了提高大采高松软厚煤层综放开采顶煤采出率,以斜沟矿23113工作面为工程背景,采用FALC3D数值模拟软件对不同采高下顶煤的应力峰值及水平位移变形量进行分析,并对不同采高下的顶煤冒落状态进行研究,相关研究成果可为矿井地质条件相类似厚煤层工作面的高产高效开采提供参考与借鉴。
In order to improve the extraction rate of top coal in fully mechanized top coal caving mining of loose and thick coal seams with large mining height,taking 23113 working face of Xiegou mine as the engineering background,FALC3D numerical simulation software is used to analyze the peak stress and horizontal displacement deformation of top coal under different mining heights,and the caving state of top coal under different mining heights is studied.The related research provides reference for high-yield and efficient mining of thick coal seams with similar geological conditions in the mine.
