Roof bolting can be done by wet or dry drilling. In coal mines, it is most common to use dry drilling. In most modern roof bolters, the primary dust control mechanism is the dry collection vacuum system. The drill cuttings are drawn into a dust collector box in the roof bolter through the drill bit, drill steel, and drill head by a vacuum pump.
