District of Engineering Geological Environment Quality in Mining Subsidence Area and Appropriateness of the Surface Spatial Development

The spatial development of surface in coal mining subsidence area has the instability on geological environment, the degradation on local regional environmental and the differences at public awareness, and therefore becomes a problem of mining sustainable development. This paper takes the coal mining subsidence of Donglongmen at Mentougou in Beijing as an example, divides the quality of engineering geological environment into three levels: a good zone, medium zone and lower zone, according to the surface stability, and proposes that the first should to determinate overall space development suitability according to the regionalization area and the spatial distribution characteristic, and then to determine the spatial development strategy in different divisions according to the specific characteristics of each region. The study is significance on improving the settlement environment of mining subsidence area and on constructing a sustainable development mining area.
