Effective mining starts with accurate drilling. That means drilling every hole precisely to plan, at the proper angle and the correct depth. Cat® MineStar™ Terrain for drilling provides precision guidance that helps operators complete patterns accurately and productively. It pays other dividends, as well, by improving safety, reducing costs and recording data about drilled stratification to aid in planning blasts and improving fragmentation. And it works with all brands of drills and communicates seamlessly with MineStar and other mine management systems.
