| Abstract: |
| Ore hauling, ore pillar recovering and roof management are three major technological problems encountered in mine of inclined and gentle ore bodies of medium thickness. Such problems can satisfactorily be solved by inclined-back (wall) hydraulic filling method of coarse sizeflushing. This paper systematically describes this new method, including mine planning, ore block parameters, stopping experience and all economic and technical performances obtained. It also offers suggestions and proposals for solving the problems existing with this method to improve the technology. |
