Blasthole drilling is one aspect of open-pit mining that engineers identified long ago as a promising area for autonomous operations. Unlike haulage and loading operations, which are much more dynamic and complex with several pieces of equipment interacting in a 3-D environment, drilling a blasthole pattern on a bench is a very repetitive process.
