High-performance drilling system not only achieves efficient drilling, but also has good drilling tool economy and equipment reliability. Comfortable operating environment and various automatic functions enable operators to concentrate on safe, fast and accurate rock drilling.
Hubei Sanning Mining Co., Ltd. operates a phosphate mine. Due to the characteristics of horizontal organization's ore bodies, a Taishan Tevik DD211L driving jumbo was introduced in March 2016. With the high-performance drilling system and practical safety functions, the flexible and lightweight DD211L driving jumbo challenged the mining of thin ore bodies in a 3.5-meter-high roadway, helping Hubei Sanning Mining Co., Ltd. to meet the challenging demand of Tiaoshuihe phosphate mine in Yichang.
