摘要
应用中深孔光面爆破技术,能够缩短辅助作业时间,提升单循环进尺,在保障安全及掘进质量的基础上,可有效提升掘进速度。结合对煤矿岩石巷道掘进工程过程的调查研究,集中介绍了中深孔光面爆破技术在煤矿岩石巷道掘进中的应用。
The application of medium deep borehole smooth blasting technology can shorten the auxiliary operation time, improve single penetration, and effectively improve driving speed on the basis of ensuing the security and drivage quality. This paper focused on the application of medium deep borehole smooth blasting technology in the coal rock drivage combined with the research on the coal rock drivage engineering process.
