Study on Support Technology of Deep Mine Roadway in Xingdong Coal Mine
Abstract Because of the large depth of the mine, the original use of bolt, mesh and spray composite support, the roadway shrinkage deformation is more serious, which not only affects the use but also endangers the safety of production. According to the deformation of surrounding rock and the characteristics of engineering technology, the following three different supporting technologies are adopted: the combined reinforcement technology of bolting and shotcreting grouting, the support technology of anchor cable on the floor, and the support technology of fully enclosed U-shaped steel ring support. The research results are applied to the field engineering practice. The monitoring results show that the fully closed U-shaped steel ring support technology has the best supporting effect, the roadway deformation meets the production requirements, the roadway renovation time is longer, and it can meet the requirements of the surrounding rock of the roadway with a depth of one kilometer.
