下峪口煤矿的灰色评价研究

Grey Evaluation on Xiayukou Coal Mine

煤矿瓦斯爆炸事故的预防是煤矿安全工作的重点。针对影响下峪口煤矿采煤风工作面安全的因素具有随机性、模糊性和不确定的特点,利用层次分析法构建采煤面的安全评价指标体系,确定各指标的权重,并采用灰色评价法建立了评价模型,对其进行综合评价。评价结果表明计算得到的结果与实际情况相符,表明灰色层次分析法对煤矿安全发展具有重要的意义。

The prevention of coal mine gas explosion accident is the focus of coal mine safety work. According to the factors of Xiayukou coal mine working face safety wind under the influence of randomness, fuzziness and uncertainty characteristics, using analytic hierarchy process to establish the safety evaluation index system of coal mining face, determine the weight of each index, and the evaluation model is established by using grey evaluation method, carries on the quality synthetic evaluation. The evaluation results show that the calculated results are consistent with actual situation, show that the gray analytic hierarchy process has important significance for the development of coal mine safety.
