Abstract
Apparatus for removing solids such as coal from the discharge end of a continuous mining machine in the form of a slurry. The apparatus includes an inner sump for water and mined coal to form a slurry. A high capacity pump is in the bottom of the inner sump and has a capacity sufficient to maintain a uniform level of water in the sump and to pump the heavier solids settling to the bottom of the sump. The mined coal is supplied to the inner sump to be formed into a slurry by the water kept in a state of high agitation by the entrance angle of the water and the coal discharged therein. An outer sump extends about and fully contains the inner sump and has side walls substantially higher than those of the inner sump to collect the overflow from the inner sump in the form of dirty water and fines. A low capacity pump takes the overflow of dirty water and fines.
