摘要
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。
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.
