<br />' 2.4 THE COMPOSITE MATERIAL <br />' The material to be disposed of will initially be delivered to a <br />holding bin, and will be blended as it is re-slurried for disposal. <br />The resulting material will be a mix of the streams that produce <br />the disposal material. In the event that the mix does not meet the <br />specification for disposal material set out below (or subsequently <br />modified based on the actual nature of the disposal material <br />' encountered), inert material such as gravel will be added to the <br />slurry to bring it into compliance with that specification. <br /> <br /> 2.4.1 Nature of the material to be disp osed <br /> <br /> The material to be disposed will be a m ixture of the components. <br />' Based on the above description s, the expect ed material to be <br /> disposed of will have approximately the following average <br />' composition and expected maximum tonnage: <br /> SOURCE ASH COAL $ PRODN TONS (MAX) <br />' <br /> HANGINGWALL 90$ 10$ 2$ 20,000 <br />' FINES 10$ 90$ 1$ 10,000 <br /> ASH 75$ 25$ 2$ 20,000 <br /> <br /> TOTAL 68$ 32$ 5.0$ 50,000 <br />As can be seen, it is expected that the average disposal material <br />will have about 1/3 coal and 2/3 incombustible materials. <br />2.4.2 Quantity of disposal material <br />' The quantity of material to be disposed of is computed in the Table <br />above, and is expected to peak at a maximum of about 50,000 tons <br />' Adrian Brown Consultants -9- 1145/900820 <br /> <br />
