摘要
在安庆铜矿120m高阶段大直径强化开采试验研究中,为优化矿柱回采顺序,研究矿柱回采过程中两侧充填体的稳定性,根据矿山实际情况,应用相似原理,进行了相似材料模拟实验。实验结果表明,矿柱回采顺序应从矿体中央向两翼间隔推进;回采过程中两侧充填体总体上是稳定的;回采后应及时对空区进行尾砂充填。
In the experimental study of 120m high-level large-diameter long-hole mining at the Anqing copper mine, in order to optimize the sequence of mining pillars and research the stability of pillars on both the sides of fill during mining pillars, according to the practical conditions of the mine and similarity principle, the simulation experiment of mining had been carried out with similar materials. The experiment results indicated that the excavation of pillars should be stared at the center of the orebody and then simultaneously be progressed toward the each side of orebody to alternately extract the pillars; the fills on both the sides of pillar were stable during mining pillar; the mined-out space formed by excavating pillars should be filled in time.
