基于层次分析法的矿井煤自燃危险性模糊评价

为了能够客观、科学的对煤矿开采过程中煤自燃火灾进行有效的预防,综合运用系统工程理论、层次分析法和模糊数学方法建立了煤自燃的危险性综合评价模型。从"人-机-环-管"系统原理角度出发,建立了多层次的煤自燃危险性评价指标体系,并采用层次法对各层次评价指标的权重进行了计算,确定了5类判断指标用于评价煤自燃的危险等级。并在实践中进行应用,评价结果和煤矿实际开采过程中煤自燃发生情况基本吻合,表明了该模型是合理可行的,能够实现对矿井煤自燃危险性进行评价。

Fuzzy evaluation on risk of coal spontaneous combustion based on AHP

In order to objectively , scientifically and efficiently prevent coal spontaneous combustion during the mining, a comprehensive evaluation model about the risk of coal spontaneous combustion was established by means of the theories-system engineering , analytic hierarchy process and fuzzy mathematics .Based on ＂man-machine-environment-manage＂system theory , a multi-level evaluating index system was established for the risk .In addition , 5 categories of evaluation index were definitively used for evaluating the coal spontaneous combustion risk rank with the index weights were calculated by AHP .The actual result was consistent with the theory based on the experiments , which showed that this model can play a useful role in evaluating the risk rank of spontaneous combustion in coal mine .
