The rock drilling jumbo is widely used in underground facility construction in national defense engineering, such as underground command centers, military bases, and underground channels. It can efficiently perform drilling and blasting operations for tunneling, excavating underground shelters, or constructing underground passages. The use of rock drilling jumbos can enhance the concealment and safety of national defense engineering, ensuring the confidentiality and defensive capabilities of important national facilities. Therefore, the drilling jumbo plays a crucial role in national defense engineering.
