Working with multiple state and federal agencies, the company completed the multiphase conversion process with particular attention paid to environmental protection and compliance.
It is not possible to use identical pollution control guidelines for all refuse sites. Some types of refuse have a high pollution potential, so that extensive control measures must be employed. Other types have a lower pollution potential and therefore require less in the way of pollution control.

One of the ''cons'' is it eats up piping going through it (a friend of mine, when working as an electrician, encountered a bank building using coal ash cement; steel conduits "ate through " where they went through the wall).
) Coal will be transported directly from the mine to a holding bin via conveyor belts. The coal will then travel from the holding bin to a rotary breaker where the coal will be down sized for further washing. The over size from the breaker will exit the system as coarse refuse and will be disposed of via mobile equipment within Coarse Refuse ...

Separately, they are referred to as coarse and fine coal refuse. Coarse refuse is transported to a disposal facility by truck or belt line. Fine refuse typically exits the separation process in slurry form and is disposed of in abandoned mine workings, dewatered and mixed with coarse coal refuse for disposal in fills, or pumped through

The prep plant produces approximately 585 tph of coarse and fine refuse. The coarse refuse consists of refuse screen oversized material, and is transferred by refuse belts to a coarse refuse loadout. This coarse refuse stream consists of all plus 1mm refuse material, and accounts for about 500 tph (% of the plant feed).
Coarse coal refuse will be loaded from the coarse coal refuse bin into the same trucks hauling coal to the plant for transport back to the pit area. The refuse will be directly placed in areas of current backfilling and will be buried a minimum of four feet below the regarded surface of the overburden material.
Coarse coal refuse will be loaded from the coarse coal refuse bin into the same trucks hauling ... Onsite coal storage will be located, adjacent to the processing plant. A truck loadout bin will be used to load the stockpiled coal into highwaylegal, covered trucks for delivery.
through April 2, 1993, coarse coal refuse was hauled by 35ton trucks from the 500ton bin to the refuse pile. The dump trucks deposited piles of coarse refuse along the landside edge of the refuse pile. Bulldozers were used to spread the piles of coarse refuse and to push refuse over the pondside edge of the refuse pile. 25.
Many large heaps of coal mine waste in the form of shale and coal discards are present in the mining areas of the Eastern Transvaal and Northern Natal. Much of this material has been subject to spontaneous combustion which appears to have overcome some of the deleterious engineering properties associated with the natural Karoo aged sediments.

Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
