Rock excavation tools disintegrate and remove the rock from boreholes and tunnels by four basic mechanisms: thermal spalling, fusion and vaporization, mechanical stresses, and chemical reactions, as shown in Figure ''''Novel" or "advanced" drilling tools utilize exotic systems such as lasers or electron beams to melt or vaporize rock or ...
Excavation of the ground within the tunnel bore may be either semicontinuous, as by handheld power tools or mining machine, or cyclic, as by drilling and blasting methods for harder rock. Here each cycle involves drilling, loading explosive, blasting, ventilating fumes, and excavation of the blasted rock .
Openpit is one of the most common mining methods used and starts from the earth''s surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
Drilling and blasting method as a common excavation method is widely used in the underground engineering construction. However, in the complicated geological conditions, the path of blasting excavation available has limitation, and then the larger blasting vibration is produced, which influence the stability and safety of the protected structure.
