Aiming at the blindness of the current coal mine roadway surrounding rock support programme and its parameter design, in order to improve the effect of roadway surrounding rock support and meet the requirements of safe and efficient production of mines, taking the Jiaoping mining area as the engineering background, the roof strength, coal gang strength, bottom plate strength, the basic top comes to press the equivalent, mining disturbance, roadway buried depth, roadway protection coal pillar width, span height ratio, top height ratio and the maximum horizontal principal stress were selected as roadway stability master control indicators, and 16 typical roadways and chambers were selected as samples, and the weights of 10 classification indicators were determined based on the analytic hierarchy process. On this basis, the stability of the sample roadway was clustered and analyzed, and the optimal classification number was selected according to the F-statistic method to divide the sample roadway into five categories: very stable, stable, basically stable, unstable and extremely unstable, and then the cluster center of the stability of the mine roadway was constructed. Finally, based on the above theory, the stability of the surrounding rock in the 2407 return wind channel of Yuhua Mine was predicted, and the targeted support measures and parameters were proposed. The results show that the classification results of 2407 return wind channel roadway stability are in line with the actual field engineering, and the deformation control effect of surrounding rock is good, which provides a strong guarantee for the safe and efficient production of the working face.

针对目前煤矿巷道围岩支护方案及其参数设计的盲目性,为提高巷道围岩支护效果,满足矿井安全高效生产要求,以焦坪矿区为工程背景,选取顶板强度、煤帮强度、底板强度、基本顶来压当量、回采扰动、巷道埋深、护巷煤柱宽度、跨高比、顶高比以及最大水平主应力作为巷道稳定性主控指标,选取16条典型巷道及硐室作为样本,基于层次分析法确定了10个分类指标的权重。在此基础上,对样本巷道稳定性进行了聚类分析,依据F-统计量法选取最优分类数,将样本巷道划分为非常稳定、稳定、基本稳定、不稳定和极不稳定5大类,进而构建了焦坪矿区巷道稳定性的聚类中心。最后,基于上述理论对玉华矿2407回风顺槽围岩稳定性进行了预测,并提出了针对性支护对策及其参数。结果表明,2407回风顺槽稳定性分类结果符合现场工程实际,围岩变形控制效果良好,为工作面安全高效生产提供了有力保障。
