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.
There are many types and designs of drilling rigs, with many drilling rigs capable of switching or combining different drilling technologies as needed. Drilling rigs can be described using any of the following attributes.
RC drilling proved much faster and more efficient, and continues to improve with better metallurgy, deriving harder, more durable bits, and compressors delivering higher air pressures at higher volumes, enabling deeper and faster penetration. Diamond drilling has remained essentially unchanged since its inception.
