Abstract: The deformation failure of the galleries in unfavorable rock formations in Jinchuan is well-known in China, which is the crux affecting the production costs and the mining construction of Jinchuan Nonferrous Metal Company. The company, for many years, has invited a great number of researchers from dosens of scientific institutes, univeisities and engineering design departments to tackle this crux problem, centering on controlling the earth pressure on the galleries and obtained a certain number of significant achievements. However, to have a real grasp of the earth pressure law of Jinchuan unfavorable rock formations and to make a set of measures to control effectively the pressure acting on the galleries in a ruptured rock mass with a high geostress, one must carry out further thorough research. What is described in this paper is an example to tame the deformation failure of the Jinchuan galleries in a high-stressed ruptured rock mass by means of secondary supporting method using the spout anchorge supporting system.
