摘　　要：由于目前的围岩稳定性评价方法中样本数据的实时性不强,导致数据来源不够全面,影响了矿区回采巷道围岩稳定性评价效果,因此本文基于CMS探测技术,对矿区回采巷道围岩稳定性评价方法展开研究。根据矿区实际情况采用CMS探测技术获取回采巷道扫描数据,转换原始数据格式;根据扫描数据选取围岩稳定性评价指标,过滤不重要的影响因素,检验指标选取的合理性;确定矿区回采巷道稳定性评价指标权重,通过层次单排序处理判断矩阵,划分矿区回采巷道围岩稳定等级,建立隶属度函数,得到矿山回采巷道围岩稳定性评价结果。该矿区隶属度综合得分为0.25,属于比较稳定等级,地质条件和围岩变形是巷道围岩稳定性的重要影响因素,需要加强监测使巷道围岩具有较好的稳定性,本文方法能够较为客观地反映矿区回采巷道围岩稳定性情况,具有可靠性。Due to the poor real-time performance of the sample data in the current surrounding rock stability evaluation method, the data source is not comprehensive enough, which affects the evaluation effect of surrounding rock stability of the mining roadway. Research on rock stability evaluation methods. According to the actual situation of the mining area,the CMS detection technology is used to obtain the scanning data of the mining roadway, and the original data format is converted;according to the scanning data, the stability evaluation index of the surrounding rock is selected, the unimportant influencing factors are filtered, and the rationality of the selection of the index is checked;the stability of the mining roadway is determined. The weight of the evaluation index is processed through the single-level single-ranking processing judgment matrix, and the stability level of the surrounding rock of the mining roadway is divided, and the membership function is established to obtain the evaluation result of the surrounding rock stability of the mining roadway. The comprehensive score of the membership degree of this mining area is 0.25, which belongs to a relatively stable level. Geological conditions and surrounding rock deformation are important factors affecting the stability of the surrounding rock of the roadway. It is necessary to strengthen monitoring to make the surrounding rock of the roadway have better stability. The method in this paper can be more objective. It can reflect the stability of the surrounding rock of the mining roadway and is reliable.
