摘要
河东煤田主要煤系地层二叠系山西组普遍发育1号和2号两层可采煤层,层间距5~20 m,2号煤的开采不同程度上要受到顶板1号煤采空区积水的影响。针对这一问题,结合保利裕丰煤业2号煤掘进时,成功疏放1号煤采空区积水实例,分析研究上覆煤层采空区积水疏放方案,总结方案经验,为同类水害隐患提供科学的治理依据。
Hedong coal field ajor coal-bearing strata Permian with Shanxi group normal development of No.1 and No.2 two layers of recoverable coal,interlayer spacing 5~20 m,No.2 coal seam mining was influenced by No.1 coal seam goaf water.Based on the problem,combined with successful water discharge of No.1 coal seam goaf water in No.2 coal seam mining of Baoli Yufeng Mining Industry,the water discharge was summarized,providing scientific data for solving similar water hazard of mine.
