摘　　要：中深孔爆破技术以其显著的优点而被认为是目前煤矿井下岩石巷道掘进首选的爆破技术。为提高单循环进尺和掘进速度,在满足煤矿井下爆破安全要求的前提下,通过对直眼掏槽、斜眼掏槽等各种掏槽方式进行分析研究,提出应尽可能简化掏槽形式。以实例证明,菱形直眼掏槽和加强的楔形斜眼掏槽均能获得较好的掏槽效果。The mid-deep hole blasting technology with its significant advantages is considered as the preferred technology in coal mine rock tunneling.In order to improving drifting footage and drifting speed,and satisfying the safety underground blasting in coal mine,the parallel cut,inclined cut and other cutting types were analyzed and we propose simplify the cutting type as far as possible,Both diamond straight cutting and strengthening wedge Inclined channel were proved get better cutting results with example.
