The blastholes close to the design outline of the roadway section are the 8 peripheral holes Z14~Z21, and the peripheral holes are the blastholes where the surrounding rocks of the roadway are blasted to form the design outline of the roadway section. Evenly arranged between the cutting hole and the surrounding holes are 8 auxiliary holes, also known as caving holes F6-F13. The auxiliary holes are blastholes where a large amount of rock falls and the cutting is continued to expand. There are many other forms of blasthole distribution on the roadway excavation face, but the position of the peripheral holes that form the profile of the roadway section does not change much, and they are all near the edge of the roadway section, while the distribution of cut holes, hollow holes and auxiliary holes are concentrated in the center of the excavation face. At present, blastholes are usually drilled by manual drilling. For example, multiple blastholes are drilled on the roadway excavation surface according to the blasthole position shown in Figure 1, and then explosives are filled in the blastholes.
