摘　　要：山东新巨龙能源有限责任公司龙固煤矿投产多年来,经过水文地质条件分析,确定为水文地质复杂类型矿井,现有排水系统难以满足矿井排水需求。根据矿井排水系统现状,提出了井筒敷设排水管与直排钻孔相结合的排水方法,通过扩建排水泵房、扩建排水仓增加水泵数量及增设直排钻孔排水管路的方法来提高矿井的排水能力,满足了矿井安全生产的需要。Since Longgu Mine of Shandong Xinjulong Energy Company Limited was in production several years,with the analysis on the hydrogeological condition,the mine was determined as a hydrogeology complicated type mine and the available mine water drainage system could not meet the requirement of the mine water drainage.According to the state of the mine water drainage system,a water drainage method combined with the water drainage pipes set in the mine shaft and the direct water drainage boreholes was provided.With the water drainage pumping chamber expanded and the water drainage sump expanded,a method with the water pump number increased and the water drainage pipelines of the direct water drainage boreholes increased could be applied to improve the mine water drainage capacity and could meet the requirement of the mine safety production.
