瞬变电磁法在1304工作面顶底板水探测中的应用

Application of Mine Transient Electromagnetic Method in Detection of Water in Roof and Floor of NO.1304 Face

为了了解1304工作面顶底板的水文地质资料,确保工作面的安全生产。使用PROTEM47瞬变电磁系统,采用共面偶极方式布置线圈,对1304工作面顶底板赋水性进行探查,并分析了瞬变电磁法在1304工作面探测过程中的影响因素,得出了顶底板含水裂隙发育,工作面顶底板的富水异常区,为工作面安全回采提供了可靠的技术支持。工作面的回采资料表明,瞬变电磁法探测工作面顶底板富水性具有较高的准确性。

In order to understand the hydrogeological data of 1304 working face,to ensure the safety production of working face.Using PROTEM47 system to detect the roof and floor aquosity of No.1304 working face with the coil arrangement mode of common face and dipole and analyzing the influencing factors of transient electromagnetic method in NO.1304 working face.Obtained the water-bearing fissures developed in the roof and floor,abnormal water zone existed in roof and floor of working face and provided reliable technical support for the safe mining of the face.The data of the coal mining face showed that using TEM method to detect the roof and floor aquosity of working face has higher accuracy.
