【摘要】：为有效防治煤层底板水害,揭示多因素影响下煤层底板突水的非线性动力特征,应用具有多目标多准则决策分析的AHP法,定量分析了各主控因素控制底板突水的权重比例。以三河尖矿为例,在确定影响17号煤层底板奥灰突水的7大主控因素基础上,建立了层次结构模型;通过构建判断矩阵,进行了层次单排序和总排序及对应的一致性检验;最终确定了7大主控因素控制17号煤层底板奥灰突水的权重;以此为基础进行的17号煤层底板奥灰突水脆弱性评价结果与实际吻合效果好。进一步应用基于矩阵运算的Matlab软件,研发了AHP法权重计算系统,其操作简单,实用性强,为AHP法的推广应用提供了基础平台。
[Abstract]:In order to effectively prevent and cure the water hazard of coal seam floor and reveal the nonlinear dynamic characteristics of water inrush in coal seam floor under the influence of many factors, the weight ratio of each main controlling factor controlling water inrush is quantitatively analyzed by using AHP method with multi-objective and multi-criteria decision analysis.Taking Sanhejian Mine as an example, on the basis of determining 7 main control factors that affect the water inrush of Ordovician ash in the floor of No. 17 coal seam, the hierarchical structure model is established, and the hierarchy single order, total order and corresponding consistency check are carried out by constructing judgment matrix.Finally, the weight of 7 main controlling factors to control the water inrush of Ordovician ash on the floor of coal seam 17 is determined, and the evaluation results of the vulnerability of Ordovician water inrush from the floor of coal seam 17 are in good agreement with the actual situation.Further, the Matlab software based on matrix operation is used to develop the AHP weight calculation system. The system is simple and practical. It provides a basic platform for the popularization and application of AHP method.
