[0002] Tunnels are key projects in the construction of roads, railways, and other projects. With the development of railway construction and technological advancements, tunnel excavation methods have developed rapidly. The more commonly used excavation methods include drilling and blasting, shield tunneling, and tunnel boring machine (TBM). Due to its strong adaptability to geological conditions and low excavation costs, drilling and blasting is particularly suitable for the construction of hard rock tunnels, broken rock tunnels, and a large number of short tunnels. Therefore, drilling and blasting is still a commonly used tunnel excavation method both at home and abroad.

The explosive force of the explosives is used to break the rock, thereby quickly carrying out construction. However, drilling requires a lot of manpower and material resources, resulting in a large workload for the staff. Blasting work can only be carried out after the drilling is completed, and the efficiency of tunnel blasting excavation is low. Utility Model Content
