There are three coal-mining issues that plague slurry pumps and shorten their lifespans. Abrasive Solids. Coal itself is a highly abrasive material. Coal slurry is a muddy, acidic mixture of water, coal chunks, coal fines, dust, dirt and rocks. Coal fines are coal particle size usually less than one-sixteenth of an inch.
