Abstract: According to geological and mining conditions of Zhaogu region, the characteristics of mining damage are analyzed, two kinds of schemes are actively proposed to solve safety threat of surface water problem caused by mining subsidence and ecological damage in mining area and mine production, through the analysis of comprehensive treatment of the surface water scheme in Zhaogu region, the surface water treatment model of super thick unconsolidated layer of high groundwater water level in plain coal mining subsidence area is obtained, the synchronization of coal mining and disaster control is achieved, which avoids damage difficult after treatment.
