anticipated slurry volume and the pipe material will be selected on <br />• the basis of durability and compatibility with t}~e slurry. The <br />pipe will be supported by at least two steel towers between the <br />portal bench and the dewatering plant, depending upon the strength <br />of the selected pipe material. The pipe grade will be nearly <br />horizontal between the portal bench and the dewatering building. <br />9.3.3.1.2 Crusher <br />NCIG intends to use a roll crusher as a coal breaker. The crusher <br />receives the plus 2 1/2 inch size product from the screening <br />circuit. The coal will be transported from the crusher to the raw <br />coal storage pile. <br />4.3.3.1.3 Coal Washing Plant <br />In a hydraulic mine, the actual coal washing process begins at the <br />face. Rock and coal are presorted in the clearing and Pluming <br />process which transports the coal out of the mine. Some rock will <br />remain within the production face in shallow depressions in front <br />of the feeder breaker. Depressions will be intentionally made <br />and/or deepened to trap the denser rock material as the rock-coal <br />mixture moves towards the feeder breaker and into [he flumes. <br />If washing is required, NCIG has elected to wash only the coarse <br />material. Washability tests have shown that the "near gravity" <br />portion of the coal is very minimal (less than 2$) The finer <br />size, minus 1 1/9 inch will not be washed, but rather dewatered <br />with full recovery through filters or centrifugal dryers. <br />• NCIG - Coal Ridqe #1 4-25 ABC/1145/910509 <br />Ti2-7 <br />
