A perfect combo for successful surface mining

Rotary is outstanding for drilling production blastholes, while DTH is ideal for drilling the pre-splitting and buffer holes. So now you’ll find a full range of high-quality DTH hammers and bits, available in 4-, 5-, 6-, 7- and 8-inch, to complete our range of roller cone bits. A perfect combination for successful surface mining operations.

DTH for pre-splitting and buffer blastholes

Pre-split blasting is an efficient way to minimize the damage to the pit wall, thereby increasing the wall’s stability. By using rotary rigs for drilling the large production blastholes, and DTH rigs for the smaller but deeper pre-split and buffer blastholes, you can combine the best of two worlds to improve both productivity and safety.
