In the modern coal mining plant, we often use steel cord rubber belt conveyor to move coal in underground. Underground coal mining is one of the oldest forms of mining. This type of underground mining took a lot of planning, where tunnels were built to and from ventilation shafts and rail shafts to allow for transporting coal with belt conveyor.
The transportation of coal out of a mine is usually done by a serially linked system of conveyors. It is apparent that in a serially dependent system of this type the failure of any one component (conveyor) causes the complete system to be shut down. The provision of bunkers at strategically located points in the conveyor system can result in the production of coal even in the event of failure

The conveying network begins at the underground ore storage discharge. Two ore storage bins measuring 6 m in diameter and 60 m in height control the flow of mined material onto the conveyors. Feeder conveyors move ore from the storage bins to the main conveyors.
Coal the mechanical design for the principal underground incline conveyor that brings the coal from the underground storage bunker to the mine head storage silos above ground. Description and location CDI developed the basic mechanical and control system design with its proprietary in-house software BeltStat and BeltFlex (Nordell & Ciozda, 1984).
been ﬁ eld-proven in coal mining operations in Germany. It improves conveying efﬁ ciency by extending the service life of belts, saving belt costs in new conveyors and increasing capacity in existing systems. Over the last quarter-century, most underground large belt conveyors in Germany have been equipped with TT drives.

Winter can have a profound effect on your ability to keep production up in your underground mine. Snow, moisture and subzero temps work together to keep you from moving product. Slippery conditions cause coal to slip backward on the conveyor. Ice results in motors burning up and belts tearing when conveyors are started.

Essentially an AFC is a one-sided trough scraper conveyor, the second side of the trough being formed by the coal face. Cut coal falls into this trough which has an endless chain with scraper flights attached running along the base plate and returning below the base plate in an enclosed lower section or "race".
Nearly all underground coal mines use conveyor belts to transport coal. Conveyor belt entries contain large amounts of combustible materials including the conveyor belt itself, coal and coal dust, grease and oil, and roof and rib supports. The major ignition sources for conveyor belt fires are frictional heating at the belt drive or along the
Maingate Conveyor & Boot End. Because the face moves continuously along the maingate, at a steady rate if operating correctly, the required maingate belt length is continuously changing. To allow for this and to avoid too frequent stoppages to shorten the belt, it is normal for special arrangements to be made at both ends of the belt.
