These localized transport systems (shuttle cars, AFC''s, BSL''s, etc) are dealt with in following sections relative to the different types of mining. This section refers to the main transport systems out of the ...
Coal Preparation. A Coal Preparation Plant (CPP) is a facility that washes coal of soil and rock, preparing it for transport to market.
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation. Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped.

Unfortunately, in our reductionist age, too often people looking at the coal problem don''t consider the whole problem. Only by contemplating the entire life cycle of fossil energy—coal extraction, preparation, transportation, combustion, and waste disposal of byproducts—can one fully understand the enormity of coal''s toxic legacy.
Each system analyzed consists of coal mining, transportation, and electricity generation. In keeping with the cradletograve concept of LCA, upstream processes required for the operation of these three subsystems were also included in this study. Both surface and underground mining were examined, with
