ABSTRACT:
In order to concentrate coal slurry from a plurality of mine faces being pumped through a plurality of individual pipes, a shallow sump is formed by digging a trench along a mine tunnel and the individual pipes empty into the sump. The product, such as coal, is allowed to settle to the bottom where it is picked up and pumped out of the mine at a controlled concentration, thereby improving the pumping efficiency of the pipeline system.
