An underground mine consists of the portals (entrance and exits to the mines), mains, submains, panels, and working faces. The panels are the working sections of the production operation. Depending on the mining method, a working section can have one or more working faces. The mining activities that
Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary ("soft") rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic rocks (see Underground mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the
ground mine fires that were reported to MSHA during 1991–2000: 76 underground coal mine fires and 61 underground metal/nonmetal mine fires. As the table shows, friction is the most common cause of underground coal mine fires, while mobile equipment malfunction is the leading cause of fires in underground metal/nonmetal mines.
Because coal mining operations use conveyor belts extensively to move materials, you must be able to count on your mining equipment to work efficiently without unscheduled downtime. Every time you have to stop production for unexpected problems like repairs or housekeeping, profitability drops.

Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
We share your concerns for your employees when it comes to respirable dust and other health and safety risks inherent in the mining industry. Martin manufactures conveyor equipment designed to keep your product moving efficiently from the face of an underground coal mine or the high wall of a quarry, through the prep plant, to the boiler or
pertaining to flameresistant conveyor belt, fire prevention and detection, and use of air from the belt entry. Richard E. Stickler, acting assistant secretary of labor for MSHA, stated, "This final rule calls for improved flameresistant conveyor belts to better protect miners in underground coal mines"
PHOENIX is the leading manufacturer of high quality conveyor belting for the worldwide mining industry. This covers all kinds of belting for all appliions, for use underground or above ground. This super belt is 7.5km (4.7 miles) long, 1,400mm (55in) wide and 35mm (1 3/8in) thick. Tensile
Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining countries.
In a mine with drift or adit access, the conveyor transport can be all the way to surface but in a mine with only shaft access winding or hoisting of coal in the shaft is required. The use of conveyors introduces a requirement for roadways to be mined as straight as possible with changes of direction minimized as far as possible.
