Underground demolition work using blasting methods.

By applying the blasting method, underground demolition work can be carried out efficiently.

The technology that utilizes the explosive energy of explosives has been widely used in mining and civil engineering for a long time, and it can be said to be an economical and efficient method. Particularly in large-volume concrete structures such as building foundations, effectively utilizing the powerful explosive energy of explosives can yield significant results. By adjusting the type of explosives used, the amount loaded, and the blasting pattern, it is possible to fragment according to the site conditions (such as the type and size of the target object and the surrounding environment). Since it is possible to eliminate the use of breakers, the noise and vibration burden on the surrounding area can be reduced. When applying blasting methods as an auxiliary to breakers and crushers, adjusting the blasting pattern allows for a reduction in the workload of breakers and crushers by any desired ratio. Compared to conventional demolition work using heavy machinery, it becomes possible to reduce the operating time of heavy machinery, significantly decreasing fuel consumption. This enables a substantial reduction in CO2 emissions from the construction work.
