摘要
针对谢一矿4222(3)采煤工作面的上、下风巷和辅助上山受采动影响情况,对三条巷道的矿压显现进行了现场测试。分析了回采工作面上、下风巷内单体支柱工作阻力及巷道围岩变形等变化规律,提出了受采动影响巷道的支护措施,合理的控制了巷道围岩变形,保证采煤工作面的安全回采。
In view of the mining affecting the upward-downward airways and accessorial uphill of mining face 4222（3） in xieyi coal mine, in-situ survey of surrounding rock in the three roadways was done. The working resistance of single prop and the surrounding rock deformation of roadways were analyzed, this paper put forwards the support measures in the mining affecting roadways, these measures control the surrounding rock deformation of roadway and guarantee the mining face safety.
