Water Prevention and Treatment System of Shallow Buried Thin Bedrock Seam Mining Along Valleys

Shendong Tianlong Group Huoluowan Coal Mine 22206 fully mechanized working face, in addition to shallow buried depth, the adverse conditions of thin overlying bedrock and thick loose water containing layer, has the particularity that working face layout is near parallel stacking up and down with surface valleys due to mining conditions. Therefore, we taking water and sand issue in mining process as a research object, based on the analysis of mine hydrogeological conditions and water inrush, we analyzed possibility of water-inrush and sand crushing disaster in the process of coal mining. Combined with water conservation, ecological restoration and implementation of the projects, "space+time, optimized connection + water control project" control water system was proposed, the prevention and control of water engineering are discussed.
