Abstract:   To solve the technological problems of deep roadway support，in view of the specific geological and technical conditions in dip roadway of No.10 District in Caocun Coal Mine，the in-situ stress was measured，and the roadway support form and parameters under dynamic pressure were designed and optimized with the use of roadway support expert system software．Then，the new support system of high resistant and yielding property was established，which uses the high-strength yielding bolt and ribbed anchor as core，and the underground industrial tests and ground pressure monitoring were carried out．The results show that the support system with high-strength yielding bolt and ribbed anchor，which is based on the in-situ stress measurement，can increase the overall capacity of support structure，and control the deformation of surrounding rock effectively．Thus，the intended effect of support design is reached，which ensures the stability and normal use of the deep roadway under dynamic pressure．
