  • 中深孔分段凿岩阶段矿房采矿法在鑫达公司的应用……王晓峰
  • 摘 要:鑫达公司高品位矿脉多为薄矿脉,围岩极其破碎。针对其采用浅孔留矿采矿法开采存在的开采难度大、采矿损失贫化高和作业安全性差等问题,提出了中深孔分段凿岩阶段矿房采矿法开采该高品位矿脉,详述了设备选型和凿岩爆破参数的确定等。工业应用取得了矿块生产能力150~200 t/d,矿石贫化率20.5 %,采矿损失率8.9 %的良好指标,对今后中深孔凿岩爆破在薄矿脉的开采应用具有一定的指导意义。

    Applicationof  medium-long hole sublevel drillingblasting and staged ore room mining method in Xinda company……Wang Xiaofeng

    AbstractThe high-grade ore veins of Xinda company are mostly thin veins and thewall rocks are extremely fragmented.For that reason,mining with short-holeshrinkage method is difficult with high mining loss and dilution rate and pooroperation safety.In light of that,the paper proposed the application ofmedium-long hole sublevel drilling blasting and staged ore room mining methodto mine these high-grade ore veins and described in detail the equipmentselection and the determination of drilling blasting parameters.The industrialapplication achieves good index including a block production capacity 150-200t/d,ore dilution rate 20.5 % and mining loss rate 8.9 %.The research hasguiding significance to the application of medium-long hole drilling blastingmethod in thin ore veins.
