Fuzzy Comprehensive Judgment for Degree of Damaged Environment by Surface Subsidence

摘要

The multi-stage fuzzy sets theory is adopted to make a judging model on the damaged degree of environment because of coal mining. The model included five major reflecting factors. Meanwhile factor system and three stages judgment models are set up. Combined with the practice of Fuxin mining area, five surface subsidence areas are judged. The evaluated result is in according with the mine practice. So it provides a new practical method for evaluating the condition of geological hazard in mining subsidence area.
