摘　　要：平禹一矿多次发生大型岩溶水突水事故,数次淹井或淹采区,煤层底板岩溶水突水已成为威胁矿井安全生产的重大隐患。为提高水文地质条件复杂老矿山的煤炭资源开采利用水平,采用瞬变电磁法,使用地面和井下勘探,查明井田深部煤层底板灰岩(重点是寒武系灰岩)岩溶发育状况和含水层的富水性,圈定富水区(带)。研究可为安全开采提供水文地质依据。In view of the occurrence of large-scale karst water inrush accidents in Pingyu No.1 Mine,several flooded wells or flooded mining areas,karst water inrush from the coal seam floor has become a major hidden danger that threatens the safety of mine production.In order to improve the mining and utilization level of coal resources in old mines with complex hydrogeological conditions,the transient electromagnetic method is used,and ground and underground exploration are used to find out the karst development status and aquifers of the limestone(focusing on cambrian limestone)in the deep coal seam floor of the mine field.The water-rich area(band)is delineated.The research provides hydrogeological basis for safe mining.
