| 摘 要： | 粉砂状矿体是一种典型的散粒体介质，在这种介质中开挖巷道和在运行过程中的巷道维护都存在很大的困难。掌握巷道围岩的变形规律是寻求合理的巷道施工原则和支护方案的前提条件。以金山店铁矿的中段穿脉巷道及其围岩（仅指粉砂状矿体部分）为研究对象，采用多种监测手段对巷道及其围岩的受力和变形进行了较长时间的观测，通过对监测资料的详细分析，得出了粉砂状矿体作为巷道围岩而具有的独特的变形规律。

| Abstract: | Silty orebody is a typical kind of scattered medium,where the excavation and maintenance of tunnel is very difficult.That grasping the deformation laws of the tunnel surrounding rock is the precondition for searching reasonable constructing principle and supporting scheme. The middle section of tunnel in Jinshandian Iron Mine and surrounding rocks (with the silty orebody referred to,only) are taken as research object, comprehensive tunnel monitoring has been designed for the reseach purpose,the observation over comparatively long period has been conducted on the condition of the force-exerted and deformation on the tunnel and the surrounding rocks. The laws of deformation characteristic of the silty orebody as tunnel surrounding rock are obtained analytically. |
