• 2-16 <br />2.1.6 Resource Recovery <br />The operator proposes to continue extraction of portions of the Cameo Coal <br />Seam from within the permit area. Limitations on the amount of coal (that will be <br />recovered will be based upon technical and economic feasibility. These limitations are <br />discussed in the following paragraphs. Operation of the mine during the next permit <br />I <br />term will mainly be in the area east of the existing mine workings, see Figure 2.1-1. <br />Specific limitations expected to be encountered are burn exclusion zines and fault <br />barrier pillars. Quantities of coal to be extracted or excluded during the next permit <br />term are discussed in Paragraph 2.1.6.6. <br />• 2.1.6.1 Split Seam Areas <br />The Cameo seam exists as both a single and split seam within the mine plan <br />area. When evaluating the feasibility of mining multiple or split seam's, a minimum <br />interburden of 50 feet is considered necessary. Mining will be performed primarily in <br />the upper seam. Mining in the lower seam is only considered feasible in the northeast <br />corner of the permit area where the upper seam thins to less than 5 fi et. <br />I <br />I <br />2.1-6.2 Mineable Seam Heights ~ <br />As described, the Cameo Seam exists as both a single and split seam in the <br />mine plan area. The Lower Cameo has heights from 8 to 17 feet in the split seam area. <br />The Total Cameo Seam reaches 22 feet high. It is planned to mine coal from a <br />i <br />minimum height of 5 feet to a maximum height of 11 feet. In areas that are greater than <br />M`Clane Volume 1 12/99 <br />
