针对薄煤层刨煤机开采适应性和实测困难问题,运用熵值法和灰色关联理论对影响刨煤机适刨性的影响因素进行多级多层分解,以目标系列之间的关联度作为目标函数,根据归一公式进行量化递归运算,分别计算出各级的隶属函数,进而建立薄煤层刨煤机适刨性的灰色关联决策模型,并应用于实际分析。研究结果表明,该评价方法可行,适刨性预测结果与实际测试结果一致。 Aiming at the problem of thin coal plow mining adaptability and actual measurement difficulty, the paper uses entropy method and gray relational theory to make multi-level and multi-level decomposition of influencing factors affecting the plowability of plow coal machine, and takes the correlation degree between the target series as a target Function, according to the normalized formula, the recursive operation is carried out, and the membership function of each level is calculated respectively, then the gray relational decision-making model of the plowability of thin coal plow is established and applied to practical analysis. The results show that the evaluation method is feasible and the prediction results of suitable shaver are consistent with the actual test results.
