摘 要:为了实现井田一采区东部薄基岩区4#煤层安全顺利开采,通过对该区薄基岩区段松散层地质及水文地质条件进行分析研究,以确定合理采煤方法及薄基岩厚冲积层条件下防治水技术方案及措施,进而评价煤层开采的防水煤岩柱留设安全程度,提出煤层开采防排水综合技术方案,确保矿井安全生产。In order to realize the safe and smooth mining of No.4 coal seam in the thin bedrock area in the east of the first mining area of the mine field,the geological and hydrogeological conditions of the loose layer in the thin bedrock section of the mine are analyzed and studied to determine the reasonable coal mining method and the technical scheme and measures of water prevention and control under the condition of thin bedrock and thick alluvial layer,and then evaluate the safety degree of waterproof coal pillar in coal mining,the comprehensive technical scheme of coal seam mining drainage is put forward to ensure mine safety production.
