基于AHP和扩展集对理论的采空区遗煤自燃危险性评价研究

采空区遗煤自燃严重威胁着煤矿的安全生产,因此为了提前采取有针对性的防范措施,有必要进行遗煤自燃危险性评价。采用层次分析法确定各评价指标的权重,根据集对分析法的基本原理结合采空区遗煤自燃的具体情况,对集对理论进行了扩展,并重新构建了基于确定不确定信息的分析模型。将该模型应用于新集二矿210610工作面,评价结果表明该模型分析过程合理、置信度高,为采空区遗煤自燃危险性评价提供了一种新的方法,同时也为煤矿有针对性的采取安全防范措施提供了参考。

Research of risk assessment on spontaneous combustion of goaf coal based on Analytic Hierarchy Process and extended set pair theory

The spontaneous combustion of coal in goaf seriously threatens the safety production of coal mine , and in order to take targeted measures in advance , it is necessary to conduct risk assessment on spontaneous combustion of residual coal.The method of Analytic Hierarchy Process （AHP） was applied to determine the weight of each evalu-ation index .According to the basic principle of set pair analysis method and combining with the specific circum -stances about spontaneous combustion of residual coal in goaf , the set pair analysis theory was extended , and the a-nalysis model based on certainty and uncertainty information was re-constructed .The model was applied to No . 210610 working face in Xinji No .2 coal mine .The assessment results showed that the analysis process of the model is reasonable and has high degree of confidence .It provides a new method for making risk assessment for spontane-ous combustion of residual coal in goaf , and at the same time provides the reference for taking safety precautions in coal mines.
