徐州城市规划区煤矿采空区稳定性评价

Stability evaluation of goaf in Xuzhou urban planning area

徐州城市规划区内由于大规模的煤炭开采,采空区分布面积较广,随着城市建设的发展,土地资源日益紧张,煤矿采空区土地成为煤矿区可持续发展的重要自然资源。开展采空区稳定性评价,是煤矿采空区土地利用的前提。本文针对徐州城市规划区内大面积的煤矿采空区,建立了采空区稳定性评价指标体系,采用敏感因子—一般因子评价模型对采空区稳定性进行综合评定,最终划分出不稳定区、基本稳定区和稳定区。

Because of coal resources exploiting on a large scale,coal mining goaf is widely distributed in Xuzhou urban planning area. With the development of the urban construction,the land resources are increasingly lack.Coal mining goaf land is becoming the important natural resource for sustainable development of coal mining area. It is the prerequisite for the coal mining goaf land use to carry out the evaluation of stability. In this paper,the evaluation index system of goaf stability and the sensitive factor-general factor evaluation model is established according to the characteristics of large-scale coal mining goaf in Xuzhou urban planning area.Finally,the unstable region,the basic stable region and the stable region were identified. The result of coal mining goal land stability evaluation is scientific basis for coal mining goal land developing-utilization.
