Abstract:
A large amount of damage of Salawusu group aquifer caused by mining under the condition of thin bedrock and shallow buried coal seam of Shenmu Mining Area in northern Shaanxi Yulin, which causes ecological imbalance. Theory and practice has proved that this kind of crack damage affected by the mining method to a certain extent. Therefore, the influence of researching different mining methods of shallow buried coal seam on fracture development based on the principle of coordination detract is another way to solve this problem. Taking Wangjiagou Coal Mine 1301, 1302, 1303 fully mechanized coal face of Shenmu Mining Area in northern Shaanxi Yulin as an example, the coordinate mining method is applied to effectively reduce the development of conductivity fracture height.
