摘要
煤的破碎程度直接影响着煤的氧化自燃性,但实际条件下煤体的破碎程度难以定量确定.根据煤层地质构造、煤的硬度、压力参数、采煤方法和巷道参数等影响巷道煤体破碎程度的多种因素,采用专家给分的方法确定各影响因素权值,并采用多级模糊综合评判的方法对巷道煤体破碎程度进行综合评判,客观评价出其破碎等级,从而为巷道煤体自燃危险性预测和防灭火提供依据.
The coal size affects directly on spontaneous combusibility of coal, it is difficult to determine coal size which affects directly spontaneous combustibility of coal. Based on the factors, such as structure, rigidity of coal, rock pressure, mining method, parameters of roadway,influencing on coal size, the coefficient of weight of every factor is determined by experts appraise. The degree of coal size is determined impersonally with multilevel fuzzy sythesis evaluation means around roadway. It is signification for prediction of coal spontaneous combustibility and fighting selffire.
