Underground Jumbo Drilling Rig Machine Rotary Drilling Operation
An underground drilling rig performs rotary drilling operations by utilizing high-torque rotational force to penetrate subsurface layers. The rig's powered rotary head drives a drill string equipped with specialized cutting bits, which grind through soil, rock, or other geological formations. During the process, drilling fluid is injected through the hollow drill pipe to cool the bit, remove cuttings, and stabilize the borehole wall. The auger drill rod simultaneously transmits rotational energy downward while conveying excavated material upward through its helical flights. This mechanized process enables precise vertical/horizontal boring for applications including foundation piling, tunnel construction, utility installation, and mineral exploration. Modern rigs incorporate computerized monitoring systems to optimize rotational speed, feed pressure, and alignment control, ensuring operational efficiency while minimizing ground disturbance in urban or environmentally sensitive areas.
