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 top and bottom of 1304 working face hydrogeology data, to ensure the safe production of work surface. Using PROTEM47 transient electromagnetic system, coil was laid out by coplanar dipole method to investigate the water-carrying capacity of roof and floor of 1304 working face, and the influence factors of transient electromagnetic method in 1304 face detection process were analyzed. The development of water-bearing fissures and the water-rich anomaly zone of roof and floor of working face provide reliable technical support for the safe mining of working face. The mining data show that the transient electromagnetic method to detect the top floor of the work floor has high accuracy.
