Water Controlling Research of Complex Fault Structures in Wugou Mine

Abstract

Once the lead abutment pressure influence the fault structure, its internal rock mass is damaged easily while the fault structures are the most vulnerable of mining influence weak link. If the fault structures conduct the aquifer, the mine water inrush will occur. This paper researchs water level of Taiyuan limestone aquifer with three-dimensional form simulation and analyzes mine water movement characteristics and the change of water level and hydraulic contact of each aquifer combining with complex geological conditions of Wugou mine, aiming at tectonic evolution and tectonic combination characteristic of the mine, according to the long observation hole material. Combining with water pressure test results and drilling and geophysical prospecting achievement, using daubing coefficient method to analyze sealing of fault structure, we conclude that faults are pressure-torsional normal faults which their fault zone is compact and has high strength so we can narrow even do not leave set fault waterproof pillar in Wugou mine.
