Applications
This series surface dth drilling rig integrates the down-the-hole drilling system and screw air compressor system, equipped with a dedusting device. It features environmental protection, energy saving, high automation, efficient drilling, easy operation, flexible moving and safe traveling. The drill also has a high-air-pressure screw drill bit which uses the internationally leading TangshiY-shape line. The bit features large flow and high air pressure and can provide strong power for high-air-pressurepneumatic drill hammer, withthe drilling speed 20%-50% faster than that of medium-air-pressure drills. This Integrated Rock Drilling Rig is applicable to medium-deep hole drilling with extension rod in rock excavation of large- and medium-sized surface mine, quarry, highway, railway, water conservancy, electrical and construction projects. Applicable rock hardness:F=6-20, drilling diameter: 90-190mm, economic drilling depth: 12-25m.
