Along with the development of highways, railways and water transportation, more and more lines pass through Chongshan mountains and are positioned in mountain areas with more complicated and changeable terrain and topography, and the proportion of tunnels is larger. The first procedure of tunnel construction is tunneling, the quality of a tunnel excavation technology directly influences the excavation volume and the supporting concrete consumption, and excessive excavation and insufficient excavation increase the enterprise construction cost and the construction period. Therefore, in order to improve the tunneling quality and reduce the construction cost, the existing common smooth blasting tunneling construction has the defects that the force is not uniform during explosion along with the complexity and changeability of rock masses, the energy transmission loss is large, the over-excavation and under-excavation conditions still exist, and the number of drilled holes and the explosive quantity are not optimized, so that more explosives and supporting materials are consumed, the disturbance damage to surrounding rocks cannot be controlled, and the construction quality is seriously influenced. So shaped blasting is required, the so-called shaped blasting effect, when a conventional cylindrical or spherical cartridge, whether initiated from the middle or from one end, propagates with the explosive products and shock waves diffusing outward in a spheroidal shape from small to large. The movement characteristics of the device are that the pressure, speed, density and other blasting parameters decrease rapidly with the increasing of the propagation radius, and the reason is that the blasting energy is distributed in the increasing spherical volume along with the movement of the blasting products and the shock wave. If one end of the cylindrical explosive package is designed into a groove (energy collecting groove), when the cylindrical explosive package is detonated at the other end, the pressure, the speed, the density and the like are not only not reduced but also strengthened in the range of the groove. This is because the explosive products and the shock waves generated by the explosion of the explosive near the grooves are converged in the axial direction of the grooves and then collide with each other, resulting in the formation of a high-pressure, high-density, high-speed gas flow which is emitted outward in the axial direction, and this emitted gas flow is called a shaped jet, and this phenomenon and action is generally called a shaped effect.
