Controlled blasting is a technique used in construction and mining to break rock in a precise and safe manner. This method involves carefully planning the placement and timing of explosives to minimize vibrations and noise, ensuring that surrounding structures and the environment are protected. The process typically includes drilling holes into the rock, placing explosives, and then detonating them in a specific sequence. By controlling the blast, operators can achieve desired rock fragmentation while reducing the risk of fly rock and other hazards. This technique is often employed in projects involving quarries, tunnels, and road construction.
