Study and Simulation on Coal Mine Satety Assessment

Research coal mine safety problems.Because of themany factors affect coal mine safety,the traditional methods for evaluating the accuracy of the results is not strong.The paper proposed coal a mine safety evaluation model based on hierarchy analytic method combined with the approximate ideal solution ordering.First,the characteristics of coal mine production were analyzed and the safety evaluation index system was constructed with expert system.Then,the hierarchy analytic method was used to the evaluate weights to indexes.Finally,the approximate ideal solution ordering was used to calculate the security levels.Research results show that the model of the evaluation is more accurate than the conventional evaluation method,and is a kind of effective coal mine safety evaluation method.
