| description | In view of problems of fast excavation and slow supporting in traditional roadway excavation technology, anchor drill rig was introduced in Tashan Coal Mine, fully mechanized fast excavation technology of alternating with advancing or bolting was developed, and industrial test of the technology was studied. Through monitoring related parameters in technique implementation process, the following conclusions was obtained : convergence rate of around surrounding rock is less than 0.1 mm/d after roadway excavation support 60 d, explains that roadway convergence is stabile, the maximum rock bolt stress is 206 kN, anchor cable force is 305 kN, all are in the range of security. The conclusion shows that the technology can greatly improve anchoring force and control abscission layer. The technology achieves 10% attrition, improve 41% support efficiency and 33.3% drivage efficiency, which can be popularized and applied. |
