transportation coal mines

As a result, different mining operations require different transport solutions. For example, a coal mine situated close to a coal-fired power station (or rather, a coal-fired power station built near a mine) would need minimal transport and most of the extracted coal could be transported via a conveyor belt directly to the power station.
