The design has a single casing of tubing strings enclosed and filled with an inert gas to allow for leak monitoring, corrosion prevention and heat transfer. A series of horizontally drilled lateral oxidant delivery lines into the coal and a single or multiple syngas recovery pipeline(s) allow for a larger area of coal to be combusted at one time.
A coaling tower, coal stage, coaling plant or coaling station is a facility used to load coal as fuel into railway steam locomotives. Coaling towers were often sited at motive power depots or locomotive maintenance shops. [1] In the early years of railways, coal was shovelled by hand into locomotive tenders.
Surface railroad cars dumped coal into bins under the track, from which chutes led down to the tunnel. A tunnel car could be loaded with a full load of 3 + 1 ⁄ 2 short tons (3.18 t; 3.13 long tons) of coal in two seconds.

The third sector is the smallest one and it heats air which is routed into the pulverizers and used to carry the coal-air mixture to coal boiler burners. Thus, the total air heated in the RAPH provides: heating air to remove the moisture from the pulverised coal dust, carrier air for transporting the pulverised coal to the boiler burners and ...
The upper seams of coal are removed with spoils placed in an adjacent valley." "Step 3. Draglines excavate lower layers of coal with spoils placed in spoil piles." "Step 4. Regrading begins as coal excavation continues." "Step 5. Once coal removal is completed, final regrading takes place and the area is revegetated."
