摘要：In order to conserve water resources in coal mines where caving and fractured zones are induced by shallow coal seam mining, an analysis was conducted on the Ebu coal mine. Empirical relationships were observed in order to estimate the heights of the caving and fractured zones; roof breakage and falling features were simulated using physical simulations. In an attempt to better understand and prevent caved and fractured zones from destroying the water bearing layer, data from the optimized coalface, inclined length, pillar width, as well as the advanced length, were analyzed using a three-dimensional numerical simulation. The field observations of roof separation, ground surface subsidence and the water inflow were compared to the simulated data and results suggested that the tests were successful.
