为解决急倾斜煤层采煤方法的选择问题,构建了基于模糊理论的决策模型。首先按照模糊综合评判方法创建多目标决策指标体系,其次采用模糊层次法确定各指标权重,并利用模糊数学进行综合评价,计算出各决策方案的隶属度,最后根据隶属度得出决策结果。应用本模型对工程实例的3种采煤方法进行综合评判。评判结果表明:伪倾斜分层走向长壁采煤法为最优方案。
In order to solve the selection of coal mining methods in steep coal seams, a decision model based on fuzzy theory is constructed. Firstly, a multi-objective decision index system is established according to the fuzzy comprehensive evaluation method. Secondly, the fuzzy hierarchy method is used to determine the weight of each index, and fuzzy mathematics is used to make a comprehensive evaluation. The membership degree of each decision scheme is calculated. Finally, the decision result is obtained based on the membership degree. The model is applied to comprehensively evaluate the three kinds of coal mining methods of engineering examples. Judging results show that: Pseudo-tilt stratification to longwall coal mining method is the optimal solution.
