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期间防治水技术与方法,保证了沿空掘巷的安全,取得了较好的探水效果和较大的经济效益。
The first one of No. 2 coal seam in the Yungaishan mine field belongs to the soft and unstable thick coal seam. The form of the goaf formed after recovery is different. The water accumulation in the goaf is irregular, based on the characteristics of the above coal seam. Through the analysis and study of the water accumulation in the goaf, the mine in the soft and thick coal seam is put forward to prevent and control the water technology during the heading of the goaf. The technology and method ensure the safety of roadway driving along goaf, and achieve better water exploration results and larger economic benefits.
