Audited Supplier
Split Mountain tunneling jumbos have a special modular design for accurate, fast face drilling for straight holes or mechanized long-hole drilling and bolting for cavern excavation, while ensuring high productivity and reliability. Our two-boom, three-boom electro-hydraulic jumbos, w/o console, could drill holes with a diameter of 45 to 64 millimeters with a depth of up to 6.1 meters (20 feet)in high-quality tunneling excavation of 12-180 m² cross sections.
............Also whole machines for undeground mining could be supplied at one stop, like LHD , Dump trucks, scalers, face drilling rig / development rig, botlers, top hammer longhole production drill rigs. etc.
KJ321 / KJ421 two boom electro-hydraulic mining jumbo
KJ421 is a two-boom, electro-hydraulic mining development drill rig, engineered for fast and accurate drilling. This mining jumbo provides reliability of face drilling, cross-cut drilling and bolt-hole drilling in tunneling of 8-60-square-meter cross sections. Well-designed, structures and proven components ensure this mining jumbo a reliable workplace for both operators and maintenance crews. Optimised drilling control system will help to keep holes straight, reduce jammings and maximize the tool life consistently.
