摘要
用关系矩阵确定表征各影响因素在煤与瓦斯突出地位中的因素活动性指数,并利用模糊集合理论中的隶属度为量化手段确定单因素分级指数,最后综合两种指数求得反映煤与瓦斯突出的危险性系数。此方法在平顶山煤业集团预测煤与瓦斯突出中的应用表明:基于关系矩阵和模糊集合的煤与瓦斯突出综合评价是可行的。
The individual contribution of the factors to the total system of coal and gas outbursts is quantitatively assessed through the parameter'factor activity' in the form of interaction matrix. A site - specific value indicating the factor's contribution to coal and gas outbursts is assigned to each factor through the parameter 'factor values' with the application of fuzzy sets. Both the parameters are then combined to compute a coal and gas outbursts index.A case study of coal and gas outbursts is given using interaction matrix and fuzzy sets in Pingdingsan. An example showed that the method is superior to the other conventional methods.
