Tunnel Construction
In this video, we explore the fascinating process of tunnel excavation underground. We showcase a remarkable three-arm machine that is specifically designed for drilling holes in tunnels. These carefully drilled holes serve as placement points for explosives, which are utilized to excavate the tunnels through controlled detonations. One of the impressive features of the hole drilling machine is its efficiency. It is capable of creating a 6-meter hole within a mere 2 minutes, showcasing its speed
