水口山铅锌矿11011底柱回采设计方案优化

Optimization of backstoping design scheme of bottom pillar 11011 in shuikoushan pb-zn mine

水口山有色金属有限责任公司铅锌矿(以下简称水口山铅锌矿)于2003年破产重组,现阶段主要开采老鸦巢矿区的采空区残留矿体,开采条件比较复杂,地质资料缺失严重,生产状况紧张。本次设计的回采方案为11011采场端部的底柱,矿体回采时从十一中段平面往下布置采准工程;由于实际地质资料缺失严重,本次设计需要根据实际进度摸索式开展。现知矿体赋存状况良好,拟采用房柱法,巷道布置采用沿脉和穿脉联合联合巷道布置,出矿为在十一中段利用溜井溜至十二中段,放矿至矿车利用电机车集中出矿,利用六坑盲竖井运搬至九中段,再经电机车运输至二坑矿仓集中矿。

The lead and zinc mine of shuikoushan nonferrous metal co., LTD（hereinafter referred to as shuikoushan lead and zinc mine） was bankrupt and reorganized in 2003. At present, it mainly mines residual ore bodies in the goaf area of laoyaochao mining area, with complicated mining conditions, serious geological data loss and tight production conditions. The designed recovery plan is the bottom pillar at the end of the 11011 stope, and the mining preparation project is arranged from the plane of the middle section 11. Due to the serious lack of actual geological data, this design needs to be carried out by trial and error according to the actual progress. Known orebodies occur in good condition, the fitting room and pillar method, roadway layout of roadway layout using pulse joint joint along the vein and wear, the ore is in the middle of the national use of chute slipped to 12 segments, ore to car use electric locomotive concentrate ore, using six blind shaft carrying to nine middle hole, then through electric locomotive transportation to two ore bin concentrated mine pit.
