To realize safe and efficient mining in a copper-nickel mine in Xinjiang, a horizontal lateral medium-deep hole blasting mining technology was proposed. Firstly, blasting parameters are preliminarily determined by the empirical analogy method: the blast hole diameter is 65 mm, the minimum resistance line is 1.625-2.275 m, the hole spacing is 1.300-2.275 m, continuous in-hole charging is adopted, the unit explosive consumption is 0.35-0.5 kg/t, and the millisecond delay initiation interval is 25 ms. Interval stemming is adopted for blast holes, with stemming lengths of 1 m and 2 m respectively. Subsequently, the LS-DYNA finite element software was used to carry out numerical simulation analysis on horizontal lateral medium-deep hole blasting. The numerical simulation results show that rock can be effectively broken by blasting and the stability of backfill roof can be guaranteed when the minimum resistance line is 1.5 m and the hole spacing is 1.0-1.5 m. Finally, field verification tests were carried out. The results show that the shape of the drift stope after blasting is relatively regular. The predicted overbreak and underbreak volume is less than 10%, No oversize blocks or fine ore are generated, and the backfill roof remains intact, achieving favorable blasting performance.

为了在新疆某铜镍矿实现安全高效开采，提出了一种水平侧向中深孔爆破采矿技术。首先采用经验类比法初步确定爆破参数为：炮孔直径65 mm，最小抵抗线1.625~2.275 m，炮孔间距1.300~2.275，孔内连续装药，炸药单耗0.35~0.5 kg/t，微差起爆时间间隔25 ms；炮孔间隔填塞，填塞长度分别为1 m和2 m。然后，采用LS-DYNA有限元分析软件对水平侧向中深孔爆破进行了数值模拟分析。数值模拟结果表明，在最小抵抗线为1.5 m、炮孔间距为1.0~1.5 m时，爆破能有效破岩，同时能保证充填体顶板的稳定性。最后，进行了现场验证试验。结果表明，爆破后的进路采场形状较为规整，预估超欠挖量低于10%，没有大块和粉矿，顶板充填体完整，取得了良好的爆破效果。
