摘要
根据采空区煤炭自燃影响因素和自燃防治因素,建立采空区煤炭自燃危险性评价指标体系,其一级指标为煤的自燃倾向性、煤层地质赋存条件、开拓开采因素、通风因素和自燃防治因素。通过采用模糊综合评价法,确定了评价指标的权重和隶属度函数,建立了采空区煤炭自燃危险性评价模型。并采用该评价方法对顾桥煤矿1122(3)工作面自燃危险性进行了评价,评价的结果与实际情况基本一致。该评价方法为制定有效的采空区自燃防灭火措施有一定的指导意义。
According to the coal spontaneous combustion factors and spontaneous combustion prevention factors in goal, an evaluating index system is established for the risk of coal spontaneous combustion in goal. The first grade indicator is self-ignition orientation of coal, geological occurrence conditions of coal bed, mining factors , ventilation factors and spontaneous combustion control factors. By adopting fuzzy comprehensive evaluation method, the index weight and membership function were determined and the fuzzy comprehensive evaluation model was established. In the end taking the 1122 （3） working--face of Guqiao coal mine as an example by adopting this method, the evaluation results are basically consistent with the actual. This showed that the evaluation method for making effective goal spontaneous combustion fire prevention measures has guiding significance.
