Abstract In order to increase the mining efficiency and ensure the service life of the roadway, combined with the causes and current situation of roadway damage in Yangdong Mine, the deep and shallow hole combined grouting reinforcement combined with anchor net spray cable support technology and hollow anchor cable grouting construction technology were adopted to improve the overall stability of the roadway. The results showed that the experiment has achieved the expected support strength.
