Drilling rigs used for rock blasting for surface mines vary in size dependent on the size of the hole desired, and is typically classified into smaller pre-split and larger production holes. Underground mining (hard rock) uses a variety of drill rigs dependent on the desired purpose, such as production, bolting, cabling, and tunnelling.
Other, heavier, truck rigs are more complicated, thus requiring more skill to run. They re also more difficult to handle safely due to the longer 6-to-9-metre (20 to 30 ft) drill pipe. Large truck rigs also require a much higher overhead clearance to operate.
Mining drilling rigs are used for two main purposes, exploration drilling which aims to identify the location and quality of a mineral, and production drilling, used in the production-cycle for mining.
