| Abstract: | Xinlu coal mine can be mined coal seam is single, mining depth is large, coal resources almost exhausted. In order to recover coal resources and prolong the service life of the mine, the existing system in shallow part is used to carry out the remining of the stage and section coal pillars of no.11 coal seam by stages and sections. The field practice results show that the remining technology is an effective way to prolong the service life of the aging mine and has good economic and social benefits. |
