摘要
承担着国家最大镍矿资源生产基地-金川集团有限公司三分之二以上自产矿石原料生产的二矿区,采用多中段大面积连续回采,在两个采矿中段之间形成大面积水平矿柱。为最大限度地回收矿石资源,对水平矿柱矿石资源进行了回采,引起了国内各同行专家的高度重视与关注。特大型水平矿柱的开采在金川矿山尚属首次,在国内外矿山也没有先例,对于金川集团公司的可持续发展具有重要意义。本文结合金川二矿区目前水平矿柱回采形状和遇到的问题,对水平矿柱底柱回采面临的问题进行分析,提出建设性的措施,对水平矿柱矿石资源的安全、高效、合理地回收提供指导。
The Jinchuan No.2 mining area is the largest production base of nickel mineral resources in China,where the annual output of ore has broke through to 2/3 of Jinchuan Group LTD.There is a horizontal pillar between two mining levels for muti-level mining.The exploitation of horizontal pillar ore resources,for the maximum recovery of mineral resources,has attracked great attention of domestic experts.The large-scale horizontal pillar mining is firstly used in Jinchuan mine,without precedent for mine at home and abroad.It's important to the sustainable development of the Jinchuan Group LTD.By combining the horizontal pillar mining current exploits situation and the problems met at present,the technological problems faced in horizontal pillar ore mining have been discussed and analyzed in this paper,and research countermeasures have been proposed,which can provide reference for the horizontal pillar ore resources mining.
