Safety analysis of fully mechanized top coal caving under water body
MA Xin-qing
Abstract：In this paper, the coal mining safety under river for Xiachang Coal Mine is analyzed. First of all, through regional exploration, the water abundance, surface soil thickness, coal seam and structure are explored; then, based on theoretical calculation and drilling measurement, the height of water flowing fractured zone is determined; and through the analysis of aquifer and impermeable layer, the amount of precipitation and the amount of water inflow in the mine, the influence of river water on underground mining is finally determined. The result has important guiding significance for mining under river. Meanwhile, the ground subsidence is simulated using the surface subsidence software, which can provide guidance of the ground river regulation for the mine.
