Abstract：Aiming at the problems of various types of underground roadways, complex structure of roadway crossing surrounding rock, low strength of surrounding rock, high cost of roadway support and frequent repair in Xinjing Coal Mine of Huayang Group, the combined support technology of grouting and high prestressed anchor cable was proposed. After a year of observation, the roof subsidence was almost 0, the maximum displacement of the two sides was 90 mm, the maximum floor heave was 150 mm, no harmful deformation was formed, and the surrounding rock of the roadway tended to be stable. Practice showed that the scheme could significantly reduce the deformation degree of roadway, maintain the safety of roadway roof, reduce the secondary repair project of roadway, and alleviate the tension of mining connection.
