摘　　要：柳湾煤矿隐蔽致灾因素较多,针对区域情况确定隐蔽致灾因素包括采空区、老窑及构造等,通过综合分析,确定区域主要致灾因素为采空区。针对61120工作面积水问题,进行瞬变电磁法勘探,确定有1处低阻异常区,面积1031.71744 m^(2)。对异常区进行钻探,确定涌水量均比较小,最大涌水量为8.85 m^(3)/h,14 d衰减速度快,采用疏干排水措施即可满足要求。研究成果对其他采面局部开采隐蔽致灾因素治理具有一定的指导意义。Liuwan Coal Mine faces multiple hidden disaster factors.Based on regional conditions,the disaster factors identified are goaf,old kilns and geological structures.Through comprehensive analysis,the main hazard factor in the area was goaf.To address the water accumulation issue in the 61120 working face,transient electromagnetic exploration was conducted,identifying one anomalous area covering 1031.71744 m^(2).Drilling in the anomalous area revealed relatively small water inflows,with the maximum inflow rate being 8.85 m^(3)/h,and the water inflow decayed rapidly within 14 d,so dewatering drainage measures were sufficient to meet the requirements.The research findings provide valuable guidance for managing hidden disaster factors in localized mining of other working faces.
