摘要
煤矿回采工作面在回采过程中,顶底板的水害、回采煤层及回采煤层顶底板岩层的地质构造等容易造成瓦斯突出、水害等严重事故。为了煤矿的安全高效生产,必须探测回采工作面顶板的含水性和顶板以及回采工作面内部的地质构造情况。以神东某矿12407工作面为例,利用音频电穿透法、坑道无线电波透视法和瞬变电磁法三种工作面物探方法对顶板和工作面内部进行探测。通过音频电穿透法和瞬变电磁法相结合探查回采工作面顶板富水性以及地质构造情况;通过坑道无线电波透视法和瞬变电磁法相结合探查回采工作面内部富水性以及地质构造情况。三种物探方法探测成果进行相互对比分析、验证和总结,有效地探查了12407工作面顶板和工作面内部的富水性以及地质构造情况。三种物探方法施工简单、施工效率高,探测成果相互补充,有效地圈定了地质异常体的位置和范围,为煤矿安全高效生产、灾害防治提供可靠的依据。
During the mining process of coal mining working face,the water damage of roof and floor,the geological structure of the coal seam and the rock formation of the roof and floor of the mining coal seam are likely to cause serious accidents such as gas outburst and water damage.For the safe and efficient production of coal mines,it is necessary to detect the water content of the roof of the working face and the geological structure of the roof and the interior of the working face.Taking the 12407 working face of a mine in Shendong as an example,the roof and the interior of the working face are detected by three working face geophysical exploration methods:audio frequency electric penetration method,tunnel radio wave perspective method and transient electromagnetic method.The water-rich roof and geological structure of the mining face are explored by the combination of audio frequency electric penetration method and transient electromagnetic method;geological structure.The detection results of the three geophysical methods are compared,analyzed,verified and summarized,and the water richness and geological structure of the roof and interior of the 12407 working face are effectively probed.The three geophysical exploration methods have simple construction,high construction efficiency,and complementary detection results,effectively delineating the location and scope of geological anomalies,providing a reliable basis for safe and efficient production and disaster prevention in coal mines.
