| 摘 要： | 针对甲玛多金属矿二期工程现有巷道围岩稳定性分类方法无法有效指导巷道支护设计的现状,基于ShapeMetrix3D近景摄影技术的工程地质调查和围岩物理力学性质试验,建立了统计区域范围内的三维岩体质量评价模型,结合甲玛矿区二期范围内的岩体质量评价体系,给出了Ⅱ~Ⅳ岩体支护标准和支护体系,制定了Ⅱ~Ⅳ岩体的巷道支护方案和支护技术参数,形成了一套适用于甲玛矿区二期区域的可以长期使用和参考的分级支护体系标准,为甲玛矿区支护设计、施工提供技术指导,具有较高的工程应用价值。

| Abstract: | According to the classification method of surrounding rock stability of the existing roadway in the second phase of Jiama Polymetallic Mine, the current situation of roadway support design cannot be effectively guided. Based on the engineering geological survey of ShapeMetrix3D close-range photography technology and the physical and mechanical properties of surrounding rock, the statistical area is established. The internal three-dimensional rock mass quality evaluation model, combined with the rock mass quality evaluation system in the second phase of Jiama Mining Area, gives the II~IV rock mass support standard and support system, and formulates the roadway branch of II~IV rock mass. The protection plan and support technical parameters have formed a set of standard support system standards that can be used for long-term use and reference in the second phase of Jiama Mining Area, providing technical guidance for the design and construction of Jiama Mine Support, with high Engineering application value. |
