412B-1 Φ76-110mm Separated DTH Mine Drilling Rig Hole

This series of separated DTH (Down-the-Hole) drill rigs has been primarily deployed in medium and small-sized quarries, cement mines, open-pit coal mines, and preliminary site preparation work for large-scale open-pit mines. It also finds extensive application in infrastructure construction projects such as highway construction, real estate development, and other related industries.

Equipped with 3.5-inch or 4-inch DTH hammers, the rigs deliver optimal performance in drilling holes with diameters of Φ90mm, Φ115mm, and Φ138mm. They boast high drilling efficiency—characterized by fast penetration rates and stable operation—and outstanding dust collection performance, which effectively reduces on-site dust pollution and meets environmental protection requirements.

A key advantage of this series lies in its exceptional flexibility and mobility. Its compact structure and maneuverable design make it particularly suitable for construction in restricted or narrow working areas, where larger equipment may struggle to operate. To date, these drill rigs have been successfully applied in a wide range of scenarios, including mining operations, military engineering projects, road construction, water conservancy projects, and rock excavation works. Their reliable performance and adaptability have earned widespread recognition and trust from customers both domestically and internationally.
