Abstract:
The control and utilization of the coal mining subsidence area would be important measures to build the ecological civilization of the mine area and to solve the tension of the land resources. Based on an introduction on a new progress of the control study on the coal mining subsidence area, the engineering practices and the policy and regulation status, a detail analysis was conducted on the present existed imperfect legal system, the unsound organization structure, difficulty implemented control funds, lack of the effective control technology and other series of the prominent problems. According to the above problems, from the government main leading,the comprehensive control the planning leadership, the responsibility clearing up, the system insurance and other aspects, the paper summarized and analyzed the basic principles abided in the control of the coal mining subsidence areas and focused and provided the control of the coal mining subsidence area around the city, the coal mining subsidence area with water pool, the coal mining subsidence area far distance from the city and the coal mining subsidence area in the arid and semi-arid area of Western China as well as the key technology and expected achievements of the low damage coal mining and the utilization and development of the surface and underground space transformation in the resource exhausted mine. Meanwhile,the paper had a detail statement on the related policies of the perfect and improved coal mining subsidence area control. Finally, the summarization and definition were made on the achievements from the control aspects of the coal mining subsidence areas in China. The paper had a prospect on the development orientation and study key points to control the coal mining subsidence area in order to provide the idea to promote the control and utilization of the coal mining subsidence area and to scientifically study on related area.
