Tunnelling in rock using the drill and blast method is a well-established technique that involves drilling a series of holes into the rock face, loading them with explosives, and then detonating them to break the rock into manageable pieces. This method is particularly effective in hard rock conditions, allowing for precise control over the excavation process. Our Online Tunnel Engineering course offers an in-depth exploration of the drill and blast method, along with a comprehensive overview of

A jumbo drill is vital in rock tunnelling for drilling blast holes and installing rock bolts, as well as creating pressure relief and drainage holes. Its multiple, adjustable arms can drill in nearly any direction, accommodating various rock formations and tunnelling needs. The machine's ability to use different drill bits enhances its adaptability, making it efficient for diverse geological conditions and drilling patterns, thereby improving both speed and safety in tunnel construction. You can

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
