The DTH/ ITH drilling quickly became popular for production drilling in open stopping, because of its productivity, and straight hole accuracy. ITH tooling can be used for drilling up holes as well as down holes. Assuming two or three shifts/day, a single rig has a capacity of about 60,000-80,000 drilled. Therefore, to obtain high utilization a certain scale of mining is required.
ITH Toolings offered
We offer a wide range of ITH toolings for the mining industry:
ITH Drilling Technology
The straight holes capability means that ITH rigs can be employed in large-scale mines to drill hole lengths up to 75 m. This degree of accuracy allows mines to space sub-levels further apart, providing substantial savings on the development of drilling drifts.
