Abstract: The area with frequent rock burst has seriously affected the safety operation of coal mine en⁃ terprises. In order to reduce the threat of rock burst to the safety of coal mine workers，it is necessary to carry out different pressure relief and support measures of roadway. Taking 21170 face of Hongxing Coal Mine as the research area，this paper analyzes the geological characteristics and the existing problems of the original roadway support system，and puts forward a new coupling support system for mine roadway to prevent rock burst. Field measurement shows that the effect of coupling support is obviously improved compared with the original support condition of roadway after rock burst. The combined support of bolt and soft structure con⁃ trols the anchoring area of roof，prevents the displacement of roadway，strengthens the support of shallow surrounding rock and deep surrounding rock，and prevents the subsidence of roadway roof. The coupled sup⁃ port can significantly reduce the probability of rock burst.
