“…Solving mining under alluvial aquifers is beneficial to ease the supply-demand relationship of coal resources in China. Meanwhile, it remains serious safety and technical problems in mining under alluvial aquifers: (1) there are generally a number of uneven thickness of the aquifers in the alluvium with complex geological structure; when the bedrock of coal seam is thinner than the water-conducting fracture zone, the fractures may connect more alluvium aquifers, and it is likely to collapse water sand into mining working face, such as the water inrush accidents happened in mining working faces under thick alluvium aquifers in Huainan Mining Area, Anhui Province [5][6][7][8]. (2) With the development of coal mining technologies such as large mining height, top coal caving, and large mining length, the scope of roof stress destruction and the height of water-conducting fracture zone have both increased, connecting the water body that is previously untouched, such as the water inrush accident caused by separation layers in mining under the huge thick alluvium aquifers in Binchang Mining Area, Shanxi Province [9][10][11][12].…”
