摘要
应用突变理论结合模糊数学建立了煤与瓦斯突出危险性综合评价的突变级数法,并通过实例验证了该方法的可行性和有效性。该方法首先建立煤与瓦斯突出危险性综合评价指标体系、评价集和隶属函数,并借助专家打分方式对指标原始值进行归一化处理;然后利用归一公式递归计算出总突变隶属函数值矩阵,得到评价结果。
A new evaluation method combined catastrophe theory and fuzzy mathematics was established to evaluate the coal and gas outburst risk, and the feasibility and effectiveness of the method is verified by an example. The method first established coal and gas outburst comprehensive evaluation index system, evaluation sets and membership functions, and carries out normalization processing with the expert scoring methods. Then the normalized recursive formula is used to calculate the total value of membership function mu- tation matrix and the evaluation results.
