摘要:
通过矿山目前采用的单一材料堵塞的冲孔分析，利用控制变量法和对比分析法，定性地研究炮孔中应力和时间的变化规律，结合现场爆破试验，将炮孔堵塞分6种情况进行试验研究，最终得出:混合材料的炮孔堵塞相比单一材料的炮孔堵塞，具有抗剪强度高、炸药能量在炮孔中作用时间长和炸药做功能力增大等特点。现场混合材料堵塞能有效地降低冲孔现象的发生，提高炸药利用率和减少炮孔上部大块的产生。
Abstract:
Conventional single blocking material is used in blast hole in mine blasting, which could result in punching phenomenon. Variable control method and contrast analysis method were used to qualitatively analyze the correlation of stress and time in blast holes. In blasting test, blast holes were blocked by six scenarios, and it was obtained that mixed material using in blast hole has the highest anti-cut strength, the longest action time for energy of explosives in holes, and the strongest work capacity. Mixed material used as blocking materials could effectively reduce the occurrence of punching, increase utilization and reduce hole upper block.
