摘　　要：云盖山井田范围内二1煤层属松软不稳定厚煤层,回采后形成的采空区形态各异,采空区积水不规则,基于以上煤层赋存特征,通过对采空区积水规律的分析和研究,提出松软厚煤层的矿井在积水采空区下沿空掘进探放水技术与方法,保证了沿空掘进的安全,取得了较好的探水效果和较大的经济效益。In Yungaishan mine range two 1 coal seam belongs to soft and unstable thick seam mining,after the formation of the goaf shapes,gob area are irregular,occurrence features of coal seam based on the above,through the analysis and research of goaf water law,put forward the soft and thick coal seam of mine goaf tunneling technology and method in water exploration and discharge the water in goaf along the roadway driving along gob,ensure the safety,and achieved better water exploration and great economic benefit.
