Supporting scheme optimization of the contact zone of roadway based on weighted GC-TOPSIS Model

将层次分析法、Euclid距离分析法和灰色广联度分析法三者相互结合,融入到TOPSIS理想解法中,形成一种新的基于Euclid距离和灰色关联度的改进TOPSIS理想法的综合评价方法,并应用到接触带巷道支护方案优化选择中。首先运用层次分析法来确定各个支护方案评价指标的权重,再利用Euclid距离分析法中的理想解和灰色关联度分析法中的关联度各自的优点,将其相互结合起来,建立一种新的相对贴近度构造方法,并应用到加权TOPSIS理想解法中建立支护方案综合评价模型,利用该评价模型选出最优的接触带巷道支护方案,确定了玻璃钢锚杆喷锚网非对称支护为最优支护方案。对试验巷道支护后的围岩变形监测表明,玻璃钢锚杆喷锚网非对称支护具有良好的支护效果,很好的控制了矿岩接触带试验巷道的围岩变形,验证了综合评判模型在矿岩接触带试验巷道支护方案优化中的有效性和可行性,可为类似矿山矿岩接触带巷道的支护方案优选提供借鉴。

With the combination of Euclidean distance and grey correlation analysis and TOPSIS method,a new relative closeness degree is constructed based on the combination of Euclidean distance and grey correlation degree,and combined with the AHP,it is applied to the supporting scheme optimization of the contact zone of roadway.AHP is used to determine the weight of each evaluation index before establishing the comprehensive evaluation model by the weighted TOPSIS method improved by the Euclidean distance and gray correlation analysis and finally determining the optimal supporting scheme of the contact zone of roadway.A comprehensive evaluation of the proposed supporting scheme is optimized by the comprehensive evaluation model in contact zone of ore and rock of the test roadway inn Daye Iron Jianlinshan Mine.The optimal supporting scheme for the non symmetric supporting of the GFRP bolt for spray anchor net is determined.The deformation monitoring of the surrounding rock of the test supporting roadway shows that the non symmetric supporting of the GFRP bolt for spray anchor net has good support effect,it is in good control of the surrounding rock deformation of contact zone of ore and rock of the test roadway,the validity and feasibility of the comprehensive evaluation model is verified in the supporting scheme optimization in contact zone of ore and rock of the test roadway,it can provide reference for the supporting scheme optimization in the similar contact zone of roadway.
