采煤工作面顺槽煤炭自燃危险性评估

根据采煤工作面顺槽煤炭自燃的特点 ,结合矿井火灾评价指标 ,建立了工作面顺槽煤炭自燃危险性的多级多层次评估因素集。运用模糊数学的理论和方法 ,建立了煤炭自燃评估指标特征值、隶属函数及权重的确定方法。根据模糊综合评价原理提出了煤炭自燃危险性的模糊评估模型 ,并应用此模型对某矿采煤工作面顺槽煤炭自燃危险性进行了评估

Risk Assessment of Coal Spontaneous Combustion of Heading of Working-Face in Coal Mine

Based on the experience of specialists and references, a hierarchy multi-stage assessment set was constructed for the fire risk of coal spontaneous combustion of heading of working-face. The weights of evaluation indexes were determined by applying set-valued statistic. A fuzzy synthetic evaluation model for the fire risk of spontaneous combustion of heading of working-face in coal mine was set up. An applied example of this model was given in this paper. The research results show that this model is a useful method for coal mine fire management
