Abstract
The problem of maintaining the surrounding rock in deep high-stress roadway has been a major subject in coal mining. The analysis of high stress roadway supporting mechanism, and the research on high stress roadway supporting technology as well as its adaptability have important significance in improving the support technology of mine. This paper analyzes the features and reasons of the high stress roadway deformation and failure, and the high stress roadway supporting measure is put forward. At the same time the paper systematically analyzed the guided roadway pressure relief combined support technology which has been used in the transporting roadway in Taoyang Coal Mine and achieved good.
