Abstract:Reasonable water prevention and control technology can effectively control mine water damage, and accurate judgment of water conduction fracture zone development height is the premise of formulating water prevention and control plan. Taking 13102 working face of Ciyaogou Coal Mine as the engineering background, the water damage control of working face was studied by theoretical analysis and field detection.The results show that the development height of water conduction fractured zone in working face is 40 ~ 93 m by using inverted hole water injection leakage measurement method. According to the development height of water conduction fractured zone, the water damage in the working face is atmospheric precipitation and goaf accumulated water in the of No. 10-2 coal seam, which should be focused on prevention and control. The water damage prevention and control of 13102 working face in Ciyaogou Coal Mine was carried out by using the method of water detection and drainage in goaf and backfilling surface subsidence cracks.
