摘要:

本文以嘉乐泉煤矿9101工作面的实际情况为背景,采用数值模拟试验和理论计算对近距离煤层采空区下工作面顶板控制进行了研究,通过不同初撑力位于同一位置和同一初撑力位于不同位置和不同推进距离的分析,最终确定支架合理工作阻力为4694KN/架。

Abstract:

Based on the actual situation of Jialequan coal mine 9101 working face as the background, using numerical simulation experiment and theoretic calculation to research the the working face roof control of coal mined-out area under .By analysising the different initial supporting force is in the same position and the same initial support force at different locations and different distance analysis, ultimately find out the reasonable working resistance of support for the 4694KN/ frame.

Key words: in close distance coal seam, under goaf, fully-mechanized faces, working resistance of support
