The quality of roadway support in soft surrounding rock is one of the most important problems of mines. As the mining depth increases, the problem becomes more and more prominent. The 62515 track roadway of Du'erping Mine was taken as the research object, the joint support system of “bolt + steel beam + anchor cable reinforcement” was first established. The specific support parameters were determined through theoretical calculation combined with field experience. Finally, through on-site monitoring, it was concluded that the amount of surrounding rock movement of the combined support was more than 50%, lower than that of the traditional support, and the support effect was good, with great application value.
