This paper presents a successful case history of stabilizing unstable rock slopes along the main railroad in Fushun mine which is located in northeastern China. The side slopes were intercepted with terraces which support roadways for mining operations. The unstable rock slopes were stabilized using ground anchors based on the principle that unstable rock blocks can be made stable against toppling by binding them together. In most cases, the ground anchors were installed in the direction normal, as much as possible, to the orientation of the discontinuities. Also installed were anchors dipping deep into the stable zone crossing the potential sliding surface. The anchor tendons were 36 mm diameter threaded steel rods and were grouted without pre-stressing along the entire length. Each exposed end of the anchor was protected using a reinforced concrete cap. For performance monitoring of the anchor systems, eight pairs of measuring points were established along existing cracks. Each pair consisted of two points which were fixed across the crack. The relative movement between the two fixed points was monitored. Only slight movement has been detected as of today indicating that the unstable rock slopes have been stabilized successfully.
