· coal mines Positioning the main access (inclines and pits) in coal mines: optimal positioning seeks to maintain approximately constant equivalent resistance of the circuit along the life of the mine; this can be achieved by placing the main lines in the center of the area to be mined; if the central positioning is not possible, the equivalent circuit resistance will increase and also the air ...

Underground Coal Gasifiion (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasifiion of the coal takes place underground instead of in a manufactured gasifiion vessel at the Obviously ...
