“直线桶形”掏槽爆破是坑道掘进工程中一种大有使用前途的作业方法。同时也是斫岩爆破人员能够从中练出一套硬功夫的作业方法。因为它目前的炮眼深度是2.5米到4米左右，今后斫岩技术不断提高，眼深将不受限制，则每爆破一次，其坑道进尺将更加可观。所以它早已为采矿部门所使用，探矿部门也大量使用。只要是爆破技术过硬，爆破材料优良，炮眼合乎规格，管理工作又有条有理，它所显示的优越性，是其它爆破方法所不能比拟的。随着我国采矿工程和探矿工程的迅速发展，以及我国矿山机械化程度的不断提高，这一方法，将普遍为人们所使用。就拿探矿工程求高级储量的大型深远坑道来说，只要能妥善使用这一方法，竟比斜眼掏槽掘进法为强。所以对于它的研究，是大有经济意义的。
“Straight barrel” undercutting blasting is a promising method for tunneling. At the same time, it is also a method by which a rock blasting crew can practice a set of hard work. Because of its current blasthole depth of 2.5 meters to 4 meters, the future rock technology continues to improve, the depth of the eye will be unrestricted, then each blasting once, the tunnel footage will be more impressive. So it has long been used by the mining sector, prospecting department also extensive use. As long as the blasting technology is excellent, the blasting material is excellent, the blasthole is in accordance with the specifications, and the management is reasonable. The superiority it shows is unmatched by other blasting methods. With the rapid development of mining engineering and prospecting engineering in our country and the continuous improvement of mine mechanization in our country, this method will be widely used by people. Take the large-scale tunnels for prospecting for advanced reserves, as long as this method can be properly used, it is actually stronger than the method of digging in and digging. So for its research, it is of great economic significance.
