摘　　要：为了解决极近距离煤层下位煤掘进、回采时巷道变形严重的问题,采用现场调查分析和数值模拟的方法,研究总结了巷道失稳的3个主要因素。研究结果表明:五虎山矿极近距离煤层采用平错式布置较为合理,平错距离20 m左右(距煤柱);根据U形钢力学性能测试结果,经过调质处理过的U形钢,其综合力学性能远远高于普通U形钢。In order to solve the serious deformation problems when mining the lower coal roadway of the ultra-close coal seam, adopt the method of field investigation and analysis and numerical simulation, the study summarizes the instability of the three main factors of roadway. The results show that the wuhushan mine extremely close distance coal seam adopted heave type layout reasonable,heave distance around 20 m(from the coal); according to the result of U-shape steel mechanics performance test, U steel after tempering process, the comprehensive mechanical performance is much higher than ordinary U-shape steel.
