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 goaf , an evaluating index system is established for the risk of coal spontaneous combustion in goaf . 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 goaf spontaneous combustion fire prevention measures has guiding significance .
