In the drill and blast method of tunnelling, the process begins with strategically drilling holes into the rock at specific intervals along the tunnel alignment. These holes serve as blast points for explosives. In tunnelling, blasting typically starts from center points and radiates outward. The central blast creates a void, breaking up the core of the material and forming a cavity. The drill and blast method remains a widely employed technique in tunnel construction due to its adaptability to
