| 摘 要： | 金川矿区岩石力学与巷道支护的研究已有几十年的历史，但是随着矿山开采深度的增大和大面积开采的采动影响，深部巷道围岩表现出明显的碎胀蠕变特性，巷道支护问题己成为矿区可持续发展的关键，通过分析巷道围岩的应力规律、特性，以及对目前使用支护形式的分析，提出深部巷道围岩的支护对策。

| Abstract: | The study on the rock mechanics and tunnel support has tens of year's history. With the increase of mining depth and the large area mining, the surrounding rock of deep tunnels exhibits an apparent crack-expansion creep characteristic and the tunnel support issue has become the key of mining sustainable development. Through the analysis of the stress law and characteristic of the surrounding rock of tunnel and the existing support modes, measures for supporting the surrounding rock of deep tunnel are given. |
