结合模糊数学和多目标决策理论,运用层次分析法建立了评价采空区自燃发火危险性的指标体系和评价模型。并根据该模型对山东龙口矿业集团公司梁家煤矿4410综放工作面采空区的自燃发火危险程度进行了定量评估,由此来确定其自燃发火危险性,从而为合理预防采空区自燃发火提供了科学依据。
Combining with fuzzy mathematics and multi-objective decision-making theory, an index system and evaluation model for evaluating spontaneous combustion risk of goaf are established by using analytic hierarchy process. According to the model, the risk of spontaneous combustion of goaf in 4410 fully mechanized caving mining face of Liangjia coal mine in Shandong Longkou Mining Group Corporation was quantitatively evaluated to determine the risk of spontaneous combustion, so as to reasonably prevent spontaneous combustion of goaf, Provide a scientific basis.
