Dynamic Safety Evaluation and Risk Degree Judging of Coal Mine

摘要

Coal mine accident system with complex space distribution and nonlinear dynamics characteristics was determined by geological condition, mining action, the human machine environment-based system and other factors. Combined with fuzzy mathematics synthesis theory, safety evaluation index system and evaluation pattern and tendency analysis pattern were formed and dynamic safety evaluation method on trend variation was put forward, which overcame the limitation of static safety method and further took a very important role in risk forecast, accident precaution and safety management. At the same time, all kinds of the risk degree were decided by the composition of comparison matrix and evaluation matrix of accident factors, which supplied the theory for the safety management and accident precaution of the coal mines.
