Abstract: In order to investigate the reasonable control method to soft broken rock roadway, taking Shanxi Xindingtai Coal Mine 2^# soft broken seam track roadway as the research object, using the combination methods of on-site investigation, numerical simulation and theoretical analysis, the article explored the roadway damage causes, processes and coupling support parameters under broken and soft rock conditions, and numerical simulation and industrial test of the support were evaluated. The results showed that roadway roof and floor easily become damaged key parts of instability, so that the two walls withstood greater loads and spalling damage occurred, and further weaken the supporting role of the roof, and formed a vicious cycle of destruction. Based on that support body and the rock strength and stiffness are not coupled, which is extremely difficult to determine the use of U-shaped steel anchor net shed and joint support form. Findings are successfully applied for 2^# soft broken rock seam track roadway at Dintaixin Mine.
