摘要
通过对水平超深孔松动爆破的参数进行研究,从最小抵抗线、炮眼深度、炮眼密集系数以及装药量等方面进行优化,并通过在内蒙古乌拉特中旗温明地下煤矿1301综采面进行的现场试验,进一步完善了超深孔松动爆破技术,从而大大降低了采煤机的切割难度,提高了矿井生产效率。
Based on the study of loosening blasting with super-deep horizontal hole, the parameters of minimum burden, hole depth and hole concentration coefficient and charge amount were optimized, and the site blasting test was also performed in the region of No. 1301 fully mechanized face of underground coal mine in Wulate Middle Ban- ner, Inner Mongolia. The loosening blasting technology with super-deep hole was further improved, which reduced the difficulty in coal winning machine cutting and improved the mine production efficiency greatly.
