[0002] Tunnels are the focus and key projects in the construction of roads, railways, etc. With the development of railway construction and the advancement of science and technology, tunnel excavation methods have developed rapidly. The more commonly used excavation methods are drilling and blasting, shield method and tunnel boring machine method. Due to the strong adaptability of the drilling and blasting method to geological conditions and low excavation cost, it is particularly suitable for the construction of hard rock tunnels, broken rock tunnels and a large number of short tunnels. Therefore, the drilling and blasting method is still a commonly used tunnel excavation method at home and abroad.
[0003] When constructing a tunnel, a blasthole is first opened in the rock wall, and then explosives are placed in the blasthole. The explosives are then detonated to achieve tunnel excavation. In this process, the explosives are mostly stuffed into the blasthole manually. However, the blasthole opening process is relatively rough, leaving a large number of uneven surfaces on the inner wall of the blasthole, which makes it easy to scratch the workers' hands when inserting the explosives.
