ABSTRACT
In order to control the harmful deformation of deep roadway, analysis is made based on the engineering background of haulage rise in one Mine. This roadway is a typical deep rock, of which the surrounding rock becomes extremely unstable, showing strong anti-symmetrical deformation characteristics and high deformation rate after excavation. According to characteristics of great ground pressure, large deform-ation and difficult in supporting deep-seated roadway, this study proposed the surrounding rock control technology of step-by-step strengthen co-supporting and optimize the parameters of roadway support. Field monitoring show that the new method obtained good effect and its a kind of effective method to controlling large deformation of surrounding rocks of deep roadway.
