<br />UPPER CAMEO SEAM <br />Initial exploration and development has mainly occurred in the Total Cameo <br />Coal Seam. A small area of Lower Cameo was mined near the end of the OOt North <br />i <br />i <br />Section. Mine design has been based on recovering the most consistent seam in those <br />areas where more that one seam exists. As is shown on Figure 2.1-6, The Upper <br />2-19 <br />Cameo Seam appears to reach minable thickness in areas of the McClave reserves. <br />Additionally, some of the thicker areas do have more than the required 50 feet of <br />interburden between the upper and lower seam. There may be areas wh~~re both <br />I <br />seams can be mined. <br />i <br />The information available at this time regarding the lower Cameo 8~eam is <br />i <br />• insufficient to identify economic areas of two seam mining. The operator will be <br />I <br />evaluating the possibility of two seam mining on a continuing basis. When the main <br />and submain entries are driven to the permit boundary, underground idrilling in split <br />seam areas will be used to determine if the lower seam is economically minable. The <br />drilling will occur in conjunction with entry development. Holes from entries in the <br />upper seam will be periodically drilled to the lower seam. If this drilling determines that <br />an economic reserve exists, permitting and development of slopes to;accE;ss the lower <br />seam will be undertaken It may be possible that a o rnay_be driven <br />from where the seam splits to access the lowers .The development in the lower <br />seam will be designed so that the entries and panels are directly below the workings in <br />I <br />the upper seam. i <br />I <br />I <br />• <br />M`Clane <br />Volume 1 <br />12/6/99 <br />
