摘要
以某金属地下矿山采场巷道围岩中两种典型的破裂岩石为研究对象，共取１４块有代表性的岩石试件，在ＭＴＳ８１５．０３电伺服岩石力学试验机上进行峰后循环加卸载试验，结果表明：岩石峰后出现破裂块体之间的摩擦滑移特性．峰后区ｖ（ε＿３／ε＿１）一般均大于０．５．
Based on the fourteen representative rock samples of surrounding rock of the stope drift in one iron mine, in the papert we have performed the ring loading and unloading tests with MTS815.03 rock test system. General conclusion is that the post-failure rock has friction-sliding characteristic in the fractured rock, and the v(hε_3/ε_1) is generally greater than 0.5.
