VENTILATION SYSTEM DESIGN FOR A THINSEAM MINING PANEL 15 to start the next stall. While the miner advances, mining the new production stall, the previously mined production stall can be backfilled, if backfill is being employed. This process is repeated until all of the planned production stalls in that panel are mined out.
Equipment Armoured Face Conveyor (Face Coal Haulage) Once the coal is cut, it has to be removed from the face to the maingate, so some form of coal haulage system is required.
