Abstract
The present invention is to an improved method of constructing a coal processing plant and an improved arrangement therefore. The overall cost of constructing a coal processing plant can be significantly reduced by the arrangement of the processing to terminate in an underground sump. By providing a subfloor to the plant with subterranean sumps, the overall height necessary to house a plant can be reduced significantly.
Claims9
A coal processing plant comprising:
- a ground floor constructed at a ground level of a pre-selected coal processing site;
- a housing structure provided above said ground floor, said housing having an average height of less than 25 feet above said ground floor;
- at least a plurality of coal processing subcircuits within said housing structure for processing coal;
- each of said plurality of coal processing subcircuits including at least one coal processing machine and producing at least an amount of coal slurry media;
- at least one sump receiving means defined below said ground floor for receiving a plurality of coal processing sumps;
- and
- said plurality of coal processing sumps each receiving an amount of the coal slurry media from one of said plurality of coal processing subcircuits and transporting an amount of the coal slurry media to another of said plurality of coal processing subcircuits for further processing.

A method of constructing a coal processing plant comprising the steps of:
- (a) selecting a site for constructing a coal processing plant having a ground level for constructing a coal processing plant foundation thereon;
- (b) digging at least one hole below said ground level to form walls defining said hole and a subterranean floor in said hole for receiving a plurality of sumps therein, wherein at least a portion of each of said sumps is below said coal processing plant foundation ground level;
- (c) constructing a coal processing housing on said foundation having an average height of less than 25 feet above said coal processing plant foundation,
- (d) providing in said coal processing housing a plurality of coal processing sub-circuits, each of said plurality of coal processing subcircuits including at least one coal processing machine and producing at least an amount of coal slurry media;
- (e) arranging said coal processing sub-circuits such that an amount of the coal slurry media produced by one of said plurality of coal processing sub-circuits is transferred into one of said sumps and subsequently transported to another of said plurality of coal processing subcircuits for further processing.
