Assessment of mining area´s environmental system safety by fuzzy logic

Mining area´s environmental system safety assessment is the comprehensive measure for the state and development trends of mining area´s environmental system, and it is the important basis to take specific measures to control the mining area´s environmental system safety. In this paper, under the guidance of the pressure - state - response (Pressure-State-Response, PSR), the mining area´s environmental system safety assessment index model was constructed, and using the fuzzy control theory, a comprehensive assessment model was constructed based on fuzzy logic, and the model have been verified by a coal mining area.
