To solve the supporting problem of the large section open-off cut of Wangzhuang coal mine 3502 working face, this article analyzed the characteristics of the internal and external bearing structure formed by cable anchor supporting. The active supporting technology with high pre-stress anchor cable as the core was used to determine the reasonable support parameters, and industrial test was carried out. The mine pressure observation shows that the supporting way has effectively controlled the deformation of roadway surrounding rock, and has obtained good supporting effect, which creates conditions for the equipment installation and successful extraction of"high top"large mining height working face. The supporting scheme used in the open-off cut of 3502 large section is superior in technology and reasonable in economy, which can be reference in similar conditions of roadway support practice application.
