Abstract:Based on 8.0m large mining height coal seam occurrence condition and the hydrogeological conditions of Bulianta coal mine, the connotation of the technical feasibility of the construction of the underground reservoir in coal mine is analyzed, the state of numerical simulation and theoretical calculation analysis method is applied to identify the 8.0m working face of large mining height are broken water inflow, water storage space and lead water fracture zone height. The results show that the water gap of the high working face of 12511 is directly communicated to the surface, and the crack ratio is 23.78, which meets the requirements of the construction of underground reservoir to guide the water channel. According to the analysis of overburden stratum fracture structure of large mining height working face and the boundary strata displacement path curve, the largest water of goaf is about 5058773m3, which meets the requirements of underground reservoir for storage. Bulianta Coal Mine 8.0m large mining height working face meet the requirements of water source, water capacity, guide channel conditions for underground coal mine reservoir construction, mine water storage and diversion can be realized through the construction of underground coal mine reservoir.
