Reverse Circulation drilling machine(YRRC350) is a gas-lift reverse circulation drill rig, a core drilling system that utilizes the gas lift principle and is primarily used in mineral exploration, geological surveys, and environmental surveys. Its operating principle is to use compressed air to expel drill cuttings from the borehole, ensuring a clean and efficient drilling process. This drill rig boasts strong adaptability, enabling deep drilling in complex geological conditions with high penetration rates and high core recovery rates. Suitable for dry and deep environments, it is easy to operate and highly safe, making it widely used in mineral resource exploration and assessment.
