Abstract
Based on the occurrence conditions and mining technical problems of a gently inclined medium-thick lead-zinc orebody abroad,this paper puts forward an efficient vertical slicing and subsequent filling mining method,and analyzes the technical problems existing in the successful application of this mining method.In view of the poor surrounding rock conditions in the upper wall of the orebody and the difficulty in the recovery of the lower triangular orebody,two technical solutions are put forward:the two-step mining and roof control technology and the pre-controlled roof vertical slicing and subsequent filling mining method in order to realize the safe and efficient mining of this kind of gently inclined medium-thick orebody.关键词
