Application of mine electric method to probe mine water-conducting or water-bearing structures in potential under coal mining face floor

In this paper, in order to clarify the water-rich of the coal face, the mine DC method is used to explore the mine water-conducting or water-bearing structures in potential under coal mining face floor at NO.10 Coal Seam of Cheng-He Mining Area, and analyzing on the hydrogeological rules of Ordovician limestone, and developed a series of application research preventing floor water invasion at NO.10 Coal Seam. The results show that this technology is relatively suitable for spatial positions and distribution laws detecting the mine water-conducting or water-bearing structures under coal mining face floor, and provides effective scientific basis for water prevention work of working face. The practice shows that the geophysical technology is extremely important to prevent the water inrush of working face and to guarantee the safe production in Cheng-He Mining Area.
