The Principle and Method of the Backplane Anchor in Controlling the Overall Stability of the Surrounding Rock

Article Preview

Abstract:

The purpose of the article is to introduce a kind of control theory and technology of roadway floor heave and the surrounding rock of the upper part deformation in a high stress field. On the basis of the stress state theory in the modern mechanics, this paper which uses Yang Zhuang III1 mining area coal mine hoist room as the research and experimental object proposes a backplane anchor control principle and technology of the overall stability surrounding rock from the perspective of improving the stress state of surrounding rock particles. After the site industrial test,the technology has a very significant effect on the control of global stability of the surrounding rocks, large section, soft rock roadways and chambers.
