• Sunbelt will be mining to the maximum physical and economical <br />constraints practical utilizing appropriate underground engineering <br />technologies. The projected overall recovery from the underground <br />mining of the A Coal Seam will be 68% with a projected 42% from <br />development operations and an additional 26% from underground slabbing. <br />The mining layout shown on the Mine Plan Map (Map 8) has been designed <br />to maximize the number of panels and to minimize waste of coal reserves <br />near the boundaries of the property. The main entries will be oriented <br />so that panel development can run either parallel or perpendicular to <br />the permit boundaries. Sunbelt has designed the panels so that no oddly <br />shaped or small isolated blocks will be left. <br />Although maximum recovery is an integral part of the planned mining, <br />some factors and conditions must be considered to insure the protection <br />of personnel, coal reserves and the environment. Coal reserves will not <br />be recovered in the following areas: <br /> <br />1. Areas where the coal is less than 4 feet thick will not be <br />mined because mining under such conditions is not economically <br />feasible. <br />2. Coal will only be partially extracted in the immediate vicinity <br />of the Peacock Portals. Consequently any disturbance to these <br />structures resulting from subsidence will be prevented. <br />3. Solid coal barriers will be left intact to isolate and protect <br />main entries from the mined-out panels. <br />4. Solid coal barriers will be left between certain panels for <br />fire and floor protection and to prevent gas accumulation. <br />These barriers will minimize the potential for the loss of the <br />entire coal reserve, should a fire occur. <br /> <br />2.05-13 <br />
