瞬变电磁法在山西大同富水区探测中的应用

Application of Transient Electromagnetic Method in the Detection of Water Rich Area in Datong, Shanxi

摘要: 煤炭是我国的主要能源, 是国民经济和社会发展的重要基础和保障。在煤炭的开采过程中，由于在煤层中容易形成富水区，对煤矿生产安全产生严重的威胁。因此，探测煤层中富水区的位置并加以防治，也是煤矿生产中的重要工作之一。瞬变电磁法作为勘探煤层中富水区的重要方法，它的物理依据是富水区与围岩之间存在电性的差异。本文在较为详细地阐述了瞬变电磁法的基本理论后，利用该方法对山西大同煤田中的富水区进行了探测，探明了陷落柱和断层的富水情况，以及它们之间的水力联系。

Abstract: As the main energy, the coal is the important foundation and guarantee of national economy and social development in China. In the coal mining process, because of the formation of rich water area in coal seam, it causes serious threat to coal mine production safety. Therefore, detection of coal seam water rich position and its prevention and control, is one of the important work in coal mine production. The transient electromagnetic method is an important method for exploration of coal rich water. It is based on the physical basis of the difference between the rich water and the surrounding rock. After the transient electromagnetic method is expounded in detail about the basic theory, the research of application of the method for detecting water-rich area is carried out in DaTong of ShanXi province with meaningful conclusions obtained, proving the water rich situation of collapse column and faults, and the hydraulic connection between them.
