Geological Environmental Impact Assessment of Mining Subsidence Area Based on Multilayer Fuzzy Synthetic Evaluation

Abstract:

Multilayer fuzzy synthetic evaluation is an effective method of the qualitative analysis into the quantitative analysis, and can reflect the different levels of objective things factors, avoiding the difficult to assign weights due to excessive factors. Geological environment of Jiawang coal mining subsidence area in Xuzhou was evaluated with an indices system based on multilayer fuzzy synthetic evaluation. Through evaluation, the serious damage region of geological mining of Jiawang mining subsidence area is 1918.966 hm², and the more serious damage region is 2524.088 hm², and the less affected area is 1366.971 hm². The results showed that the geological environment of Jiawang mining subsidence damage is more serious. The farmland was destroyed seriously, and water due to land collapse was quite serious, which was difficult to land reclamation. It is believed that this work may provide scientific reference for land reclamation and landscape ecological restoration of coal mining subsidence area.
