Nov 28, 2018· Coal mining has been performed since the arrival of the Industrial Revolution in the mid-18th century. Coal is used as a fuel primarily for steam-generated electrical power plants, as well as being a component of certain industrial applications, such as steel manufacturing.
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.
mining is thus advised to become familiar with all the terms used in mining, particularly those that are peculiar to either mines or minerals. Most of the mining terminology is introduced in the sections of this book where they are most applicable. Some general terms .
