Comprehensive Evaluation Analysis of Mine Gas Safety Based on Integrated Method

There are some weaknesses in the traditional safety evaluation methods, such as, slow reasoning, low accuracy and so on, so thinking of a variety of factors which affect gas safety, a gas safety evaluation index system is built, which focuses on the state of gas, mine ventilation, gas monitoring, safety management and kindling. Combining the fuzzy comprehensive evaluation method with gray correlation method and BP neural network method, taking Hei Longjiang Longmay Group as an example, a gas safety evaluation in its five mines was made. The results show that using different integrated comprehensive evaluation methods to evaluate the gas safety in the same mine, the results are different. It requires decision-makers to consider many factors and adopt more appropriate and scientific methods when making a comprehensive evaluation, which makes a right decision.
