摘要

煤矿采空区富含水对煤矿安全生产构成事故隐患,三维地震勘探技术对查明断层、采空区及陷落柱等地质构造有明显的优势,是探测煤层采空区及陷落柱行之有效的手段;瞬变电磁法则可查明构造含水情况,两种方法结合起来即可对采空区、陷落柱边界及含水情况做出探测,为煤矿开采提供技术保障。本文以探查山西北祖煤矿老窑、采空区、陷落柱破坏范围及积水情况为例,说明了利用三维地震勘探和瞬变电磁法技术探查煤矿采空区及陷落柱的具体方法,取得了可喜的成果。
Since the rich water in the gob area threaten coalmine safe production,constitute hidden trouble of accidents.The 3D seismic prospecting technique has obvious advantages to find fault,gob area and subsided columns detecting geological structure,coal mined gob area and subsided columns effective means;Transient electromagnetic method can identify the structural water,the two methods together to gob area,subsided columns boundary and Water content to make detection,Provides the technical support for the coal mining.Based on the exploration of Shanxi Bei Zu,old workings,gob area and subsided columns damage range and water situation as an example,the use of 3D seismic prospecting and transient electromagnetic method exploration method in coal mine gob area and subsided columns,made gratifying achievements.
