Fuzzy Comprehensive Evaluation of Geological Environment-catastrophe in Heshan City Coal Mining Area

This paper attempts to explore the characteristics of the evaluation index system and the evaluation model of geological environment-catastrophe in coal mining area. By analyzing the geo-environmental hazard in Heshan coal mining area, comprehensive assessment of geological environment-catastrophe was carried out using Fuzzy Evaluation Model in mine-out area for the first time. The results not only verify the feasibility of this evaluation model and index system, but also provide references for the decision-making and management, as well as plans for the recovery of abandoned mine in Heshan city.
