431 Φ115-152mm Separated Dth Surface Drilling Rig For Mining
This series of separated DTH (Down-the-Hole) drill rigs has been primarily deployed in small and medium-sized quarries, cement mines, open-pit coal mines, and preliminary site preparation for large-scale open-pit mines. They are also widely used in infrastructure projects such as highway construction and real estate development, among other fields. Fitted with 3.5-inch or 4-inch hammers, they deliver optimal performance for holes with diameters of Φ115mm, Φ138mm, and Φ152mm, while boasting high drilling efficiency and excellent dust collection performance. Thanks to their exceptional flexibility and mobility, this series is particularly ideal for operations in restricted work areas. It has been successfully applied in mining, military projects, road construction, water conservancy, rock excavation, and other sectors, thus gaining widespread recognition from customers both at home and abroad.
