CRCHI’s drilling jumbos are used for short-distance(50 m) exploration drilling and blast hole drilling in underground tunnelling. We offer jumbos with advanced technologies, such as multiple information fusion, 3D scanning, smart positioning, smart rig control, 50 m advance geological forecast and 30 m advance pipe shed construction. They can be widely used in different kinds of drifts, tunnels and culverts in fields like railways, highways, water conservancy, national defense for exploration and excavation.
