摘 要:该文以国外某缓倾斜中厚铅锌矿体赋存条件及开采技术问题为背景,提出一种高效的垂直分条嗣后充填采矿法,并对该采矿法成功应用存在的技术问题进行分析。针对矿体上盘围岩条件差、下盘三角矿体回收困难,提出双进路出矿巷道2步骤回采控顶技术和预控顶垂直分条嗣后充填采矿法2种解决技术方案,以争取实现此类缓倾斜中厚矿体的安全高效开采。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.
