针对灵台矿区回采巷道支护设计存在的参数同质化、合理性不足等问题，对回采巷道进行分类研究，进而提出差异化支护对策具有重要意义。首先，在系统分析灵台矿区回采巷道围岩地质条件与支护系统匹配关系的基础上，确定6个分类指标。其次，提出基于混合数据聚类的回采巷道分类方法，挖掘数值型指标和分类型指标的信息特征，并引入惩罚竞争机制，实现巷道分类过程中动态优化聚类数。接着，应用所提方法将37段灵台矿区回采巷道分为四类，验证方法可行性。最后，在邵寨煤业2502运输巷D段开展现场试验。结果表明：试验段巷道顶底板最大移近量为109 mm，两帮最大移近量为113 mm，围岩破坏范围小，回采巷道动态分类与差异化支护方法能够实现巷道围岩的稳定控制。

In response to the issues of parameter homogenization and insufficient rationality in the support design of the mining roadway in the Lingtai mining area, it is highly significant to conduct classification research on the mining roadway and propose differentiated support strategies. Firstly, based on a systematic analysis of the geological conditions of the surrounding rock and the matching relationship with the support system in the mining roadway of the Lingtai mining area, six classification indicators were determined. Secondly, a mining roadway classification method based on mixed data clustering was proposed, extracting the informational characteristics of numerical and categorical indicators and introducing a penalty competition mechanism to dynamically optimize the number of clusters during the classification process. Subsequently, the proposed method was applied to classify 37 segments of the Lingtai mining area's mining roadways into four categories, validating the feasibility of the method. Finally, a field test was conducted in the D segment of the 2502 transport roadway in Shaozhai Coal Mine. The results indicate that the maximum convergence of the roof and floor of the test roadway segment is 109 mm, and the maximum convergence of the two sides is 113 mm, with a small range of surrounding rock damage. The dynamic classification and differentiated support method for mining roadways can achieve stable control of the surrounding rock in the roadways.
