- W2357766246 abstract "Guangwang coal mine area,one of the two main coal production regions in Sichuan Province,located in the north of Sichuan Province.The area of this coal mine district is 420km~2,and its retained mineral reserve is 1.717×10~8t.There are 17 state-owned mines and 300 village-owned mines in this district. Their production capacities range from 3 to 30×10~4t/a,and the total productive output is 250~300×10~4t.Accumulative total of 1.2×10~8t coal have been mined for the last 40 years when mining activity started.In recent years,most of the mines switch to decline mining,the relative elevations of part mining section of some mines are already under 0m level.Currently the geological environment of the mine is gradually worsening;these occurrences is mainly demonstrated by the split,subsidence,and collapse of ground surface,the drying up of underground water,the cracking and leaning of building walls,the lowering of water tables,and the leakage of irrigations.Meantime,the mining activity has caused mudslides,slope sliding,and rock collapse.These geological hazards have deeply threatened the local economical development,and even affected the locals' quality of life and safety.We propose that a detailed investigation be conducted into the geological environmental issues of Guang-Wang coal mining district,the establishment of comprehensive planning for resource exploitation,geological environmental protection and geological hazards prevention,and the innovation of mining and tailing methods.In any case,project funding is crucial for curing the mining hazards in order to achieve the goal of long-term persistent economic development." @default.
