软岩巷道支护技术探析与实践

Soft rock roadway is mine construction and production of one of the key technical issues over the years has been rock mechanics and mining engineering attention. In recent years, soft rock roadway construction and supporting aspects of a large number of theoretical research and engineering practice. Dayan 2 Mine is a typical soft rock mines, with mining depth of the constantly increasing, roadway a very acute problem. Supporting use of conventional methods can not meet the safety needs. 2 Mine engineering and technical personnel through continuous exploration and practice, in the soft rock roadway technology, a success
