Chapter II <br />Reclaim conveyor system. <br />Function: Transports coal from storage to wash plant for processing. <br />• <br />Shuttle car. <br />Function: Transports coal from a continuous miner to the feeder breaker. <br />Feeder breaker. <br />Function: Used in a continous mining section to size and meter coal as it's going <br />onto the entry belt conveyor. <br />Entry belt conveyor. <br />Function: transports coal from the working section to the tunnel belt. <br />Truck. <br />Function: Transports men/materiel through the Adit, between surface and the <br />underground workings. <br />Hoist. <br />Function: Used to transport men/materiel into the mine through the surface portals. <br />(3) Roof Support <br />Longwall shields. <br />• Function: roof support for the longwall face. Shields advance with the longwall face. <br />Roof bolting machines. <br />Function: Used to install roof bolts, which function as permanent roof support. <br />Packwall equipment. <br />Function: Used to propel cement/aggregate mixture to provide support and protect <br />access ways to and from the face. It's necessary for the advancing longwall system. <br />The mixture goes into forms at the headgate and tailgate of the longwall, and then <br />hardens. <br />(4) Other Support. <br />Ventilation fan. <br />Function: Circulates fresh air through the mine which is essential for people in the <br />mine (to breath) and also for dilution and removal of methane and harmful gases. <br />Rockdusting equipment. <br />Function: to convey and distribute pulverized limestone on the mine surfaces. <br />Consists of pressure tanks and pipelines. Rockdusting is necessary to reduce the <br />risk of mine explosions. <br />The major equipment, and its use in surface operations is as follows: <br />E <br />
