Abstract:
In order to improve the safety of the rock burst prevention and control in the mine deep seam gateway, a theoretical analysis, numerical simulation, site measurement and other comprehensive study method were applied to establish a theoretical model of the space structure of the surrounding rock along in the deep seam gateway. The failure features of the differential sub-block in the deep seam gateway were analyzed. A model type of the rock burst failure occurred from the wedge wall structure of the roof and sidewalls along in the deep seam gateway was studied and obtained. With the deep strength rock burst danger seam gateway in Tengdong Mine as the background, an optimized design and engineering practices on the roof and sidewall support along the deep seam gateway were conducted based on the rock burst prevention and control. Thus a safety mining and driving of the driving face with the strength rock burst danger was realized and the rationality of the theoretical model was approved in order to provide the references to the coordinated control of the roof and sidewalls along the deep seam gateway with the rock burst danger.
