Abstract

Different rocks have different conduction; common coal measure rocks show different resistivity values. In general, the resistivity values of mudstone, siltstone and medium-coarse sandstone increase continuously, and the lithological changes in the vertical direction show as the increase or decrease of resistivity. The lithology changes with the direction of formation are generally small and the resistivity is uniform. When the coal measures are stable, the variation rule of vertical resistivity is basically the same, and the electrical conductivity is relatively balanced in the direction of bedding. When there are water-filled cracks in the coal measures sandstone, or when the fracture zone is cut by a fault, the good conductivity of the water body leads to obvious electrical difference between the structure and the surrounding rock. Based on the existing detection technology research, on the basis of Hydro geological data of limestone aquifers of the Buliangou mining field of Inner Mongolia, the transient electromagnetic method (TEM) is adopted to the mining face detection inside the top, bottom water condition, and get satisfactory results, it provides a solid foundation for mining design and waterproofing.
