阐述了底板破坏深度模糊综合评判决策模型的构建方法,结合实测样本数据,利用灰色关联分析法分析了底板破坏深度与采深、煤层倾角、采厚、工作面斜长、底板岩体损伤度等影响因素的相关性,确定了底板破坏深度的影响参数。利用建立的底板破坏深度模糊综合评价模型对实测样本进行分类,并利用建立的模型预测肥城煤田白庄煤矿7106工作面的底板破坏深度。通过实测结果对比,该模型具有良好的实用价值。
The construction method of fuzzy comprehensive evaluation decision-making model of floor destruction depth is expounded. Combined with the measured sample data, the gray relational analysis method is used to analyze the failure depth and mining depth, coal seam dip angle, mining thickness, working face slope length and floor rock mass damage degree The correlation of influencing factors, and the influence parameters of the depth of floor damage are determined. Based on the established fuzzy comprehensive evaluation model of floor destruction depth, the measured samples are classified and the depth of floor destruction of 7106 working face of Baizhuang Coal Mine in Feicheng Coalfield is predicted by using the established model. By comparing the measured results, the model has good practical value.
