    摘要:

    随着煤矿开采深度的加大,越来越多巷道围岩呈现软岩变形特性,变形破坏非常严重。针对石嘴山一矿深部高应力复杂软岩巷道围岩破坏特点,从地质赋存条件、水对岩石的软化影响和支护结构方面分析,制定了相应对策,提出了锚、网、喷、注全封闭联合支护,用FLAC3D2.0对支护效果进行数值模拟可视化计算,确保巷道的稳定性,对巷道支护实践有一定参考价值。

    Abstract:

    With the development of deep mining in mines, more and more collapse problems of surrounding rocks named soft rock in roadway become increasing serious. There are some characteristics of collapse of surrounding rocks for deep and complex soft rock roadway under high stress in No.1 Mine of Shizuishan. Analysis of geological condition, intenerating rock mass influencing on water and structure of support, established correlation countermeasure, and provided combined-supporting system of bolt, mesh, spray, grout. The result of supporting is visual calculated by numerical simulation with FLACW2.0. Finally, it is used to control collapse and deformation of surrounding rocks, and insured stability of surrounding rocks mass in soft rock roadway. It has a certain reference value of practicing to support soft rock roadway in deep mine.
