  • 龙首矿西二采区崩落采矿法组合覆盖层技术方案研究……安文杰,李广宽
  • 摘 要:龙首矿西二采区由机械化下向分层六角形高进路胶结充填采矿法开采拟改为无底柱分段崩落采矿法开采,因充填体的存在,一般难以自然冒落形成覆盖层。研究采用预留矿石和人造隔离层与充填体一起形成组合覆盖层的工艺方法,可达到降低矿石贫化率和采矿损失率,安全生产及处理采空区的目的,确保崩落采矿法的成功应用。

    Study onthe technical plan of the composite cover from caving mining in No.2 MiningDistrict in the west part of Longshou Mine……An Wenjie,Li Guangkuan

    AbstractThe No.2 Mining District in the west part of Longshou Mine is planned toswitch from the mechanized downward hexagon high access cement filling miningto sublevel caving with no sill pillars.Because of the presence of fillingbody,cover from natural caving is difficult to form.The study forms a compositecover with preserved ores and artificial isolation layer and the fillingbody,which lowers ore dilution rate and mining loss rate,improves safeproduction,deals with goafs and ensures the success of the caving method.
