Abstract: 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.
