摘　　要：为了充分反映矿山开采过程中开采扰动对巷道围岩质量的影响,在传统岩体质量分级RMR法的基础上引入巷道埋深、巷道存续时间、巷道高跨比、巷道间柱宽度和分段高度等5个采动影响指标,构建采动影响巷道围岩质量分级指标体系。引入拉格朗日乘子法耦合层次分析法(AHP)和CRITIC法对各指标进行组合赋权,将该组合权重导入理想点法(IPM)构建考虑采动影响的AHP-CRITIC-IPM改进RMR法(ACI-RMR法),将ACI-RMR法应用于某金属矿山进路巷道围岩质量分级并与RMR法分级结果进行对比。结果表明:部分测点的ACI-RMR法分级结果较RMR法分级结果出现等级降低或相同等级评分值下降的情况,结合工程实际证明ACI-RMR法较RMR法更能反映开采扰动对巷道围岩质量的影响,为矿山安全生产与设计提供参考。In order to fully reflect the impact of mining disturbances on the quality of roadway surrounding rock during the mining process,five mining impact indicators,including roadway burial depth,roadway survival time,roadway height to span ratio,column width between roadways,and section height,were introduced on the basis of the traditional rock mass quality classification RMR method.A mining impact roadway surrounding rock quality classification index system was constructed.The Lagrange multiplier method coupled with analytic hierarchy process(AHP)and CRITIC method was introduced to give combined weights to each index,and the combined weights were introduced into the ideal point method(IPM)to build the AHP-CRITIC-IPM improved RMR method(ACI-RMR method)considering the impact of mining.The ACI-RMR method was applied to the quality classification of surrounding rock in a metal mine drift and the classification results were compared with the RMR method.The research results showed that compared with the results of RMR method,the results of ACI-RMR method was reduced or the score value of the same grade was decreased at some measuring points.Based on engineering practice,it has been proved that the ACI-RMR method can better reflect the impact of mining disturbance on the quality of roadway surrounding rock compared to the RMR method and provide a reference for mine safety production and design.
