深部层状围岩巷道物理模型试验研究
|
摘要
伴随浅部资源的开采枯竭,深部开采的频率将会增加,并且采深也会加大。深部巷道围岩大多为沉积岩,沉积岩的层理结构面,使其变形破坏特征明显不同于均质岩体结构,给巷道的稳定控制带来了困难。鉴于此,依托WYQ1000—Ⅰ型地下工程综合试验模拟系统,对深部层状围岩巷道展开物理模型试验,研究了三种支护方式下巷道的变形破坏特征及围岩的应力演化规律,为深部开采工程提供一定的参考。
With the depletion of shallow resources,the frequency and depth of deep mining will increase. The surrounding rocks of deep roadways are mostly sedimentary rocks. The bedding structural planes of sedimentary rocks make their deformation and failure characteristics distinctly different from those of homogeneous rocks,which brings challenges to the stability control of roadways. In view of this,relying on WYQ1000—Ⅰunderground engineering comprehensive test simulation system,physical model tests are carried out for deep layered surrounding rock roadway,and the deformation and failure characteristics of roadway under three support modes and the stress evolution law of surrounding rock are studied,which can provide some reference for deep mining engineering.
