随着浅部矿产资源日益枯竭，深部开采已成为采矿行业的重要组成部分。深部开采重要的特征之一就是在“三高一扰动”下，矿山工程地质条件急剧恶化，围岩呈现显著的节理化，给深部巷道围岩控制带来巨大的困难。以三山岛金矿-900 m以下典型节理化巷道为工程背景，通过工程地质调查、文献调查、室内岩石力学试验获取基本数据，应用Dips软件进行优势结构面分组，应用Unwedge软件进行楔形体及其稳定性分析。采用RMR、Q和GSI岩体质量分级方法进行岩体质量分级并估算岩体力学参数，详细阐释锚杆加固不连续面的机理，估算巷道支护所需支护压力，并基于Q和RMR支护图表完成支护方案设计，应用RS2验证设计支护方案的有效性。在-960 m水平进行工业试验，结果表明，设计支护方案能够有效控制深部高应力节理化巷道围岩的变形破坏，为深部矿山安全高效开采提供依据。

With the depletion of shallow mineral resources,deep mining has become an important part of the mining industry.One of the key characteristics of deep mining is the dramatic deterioration of geological conditions in mining engineering under the influence of three highs and one disturbance.The surrounding rock exhibits significant jointing,which brings great challenges to the control of deep tunneling.Taking the typical jointed tunnels below -900 m level in Sanshandao Gold Mine as the engineering background,this study conducted engineering geological investigations,literature surveys,and laboratory rock mechanics tests to obtain basic data.The Dips software was used for structural plane grouping,and the Unwedge software was employed for wedge analysis and stability assessment.The Rock Mass Rating (RMR),Q,and Geological Strength Index (GSI) methods were used to classify the rock mass and estimate its mechanical parameters.The mechanism of discontinuous face reinforcement with rock bolts was elaborated,and the required support pressure for tunnel support was estimated.Based on the Q and RMR support charts,a support scheme was designed,and its effectiveness was validated using RS2 numerical modeling.Industrial experiments were conducted at the -960 m level,and the results demonstrated that the designed support scheme effectively controlled the deformation and failure of deep high-stress jointed surrounding rock in tunnels,providing a basis for safe and efficient mining in deep mines.
