摘　　要：钱营孜煤矿W3214工作面运输平巷为沿W3212工作面采空区掘进的沿空巷道,为了控制沿空巷道围岩的剧烈变形,研究了围岩控制技术。根据沿空掘巷围岩控制原理,并针对W3214工作面运输平巷具体的工程地质条件,提出高强度高预紧力锚网索支护技术方案。现场实践表明高强度高预紧力锚网索支护体系能有效控制沿空掘巷围岩的稳定性。The haulage roadway of W3214 working face in Qianyingzi Coal Mine is a roadway driving along the gob of W3212 working face. In order to control the surrounding rock severe de- formation, the surrounding rock controlling technology is studied. According to the theory of controlling surrounding rock in roadway driving along gob and in view of the specific engineering geological conditions of the haulage roadway at W3214 working face, this paper puts forwards the technology scheme of high-strength and high-prestress bolt-mesh-cable support. Field practice shows that this support system can effectively control the stability of surrounding rock in road- way driving along gob.
