Abstract: For the projects difficulties of sand inrush of thick coal seam mining under water-bearing unconsolidated strata,the paper carries out scientific analysis of hydro-geological conditions,including the lithology,thickness,and water yield property of water-bearing unconsolidated strata,reasonable size of leaving safety coal and rock pillars in thick seam slicing mining is discussed and the corresponding mining methods are decided.On the basis,the heights of caving zone and water conducted zone were predicted,mining method was decided.Based on the powerful data processing capabilities of GIS,the risk of sand inrush caused by multiple factors are analyzed quantitatively,and sand inrush risk zoning map was also drew eventually.
