• EFCI has developed the Jack O'Lantern and the underlying Red Arrow seam <br />in three (3) separate areas which are connected to the seven (7) entry <br />main system. As shown by the Mine Plan Map, (Map 17), mining advance is <br />progressing to the north, south and west from the main entries. EFCI <br />utilizes a room and pillar mining method with continuous miners, electric <br />shuttle cars, feeder-breakers, roof-bolters, and a underground belt <br />haulage system as the main production equipment. Other underground and <br />surface support equipment is utilized as necessary for material <br />excavation, haulage, cleanup, maintenance and other activities. A listing <br />of major underground and surface equipment currently utilized at the <br />Southfield Mine is presented as Table 30, Major Equipment List. <br />The mine currently operates on a five (5) day per week, two (2) shift per <br />day production schedule on a year round basis. Normal production averages <br />between 1,200 and 1,800 raw tons per shift. <br />• Within a given reserve block, EFCI begins development by extending a five <br />(5) entry sub-main system into the center of the reserve. As appropriate, <br />based upon the configuration of the reserve, panels are driven laterally <br />from the sub-mains to the limit of the reserve, maintaining 80' x 80' <br />support pillars as mining advances. As the sub-mains are extended, <br />additional panels are developed to ensure maximum recovery of the <br />available minable reserves. Once the sub-mains and panels reach the <br />limits of the reserve block, EFCI begins retreat mining recovering <br />approximately 40X of the coal remaining in support pillars while <br />retreating from the mine section. <br />Coal extracted from the working sections is transported to the surface by <br />a belt conveyor system where it discharges to a raw coal stockpile. The <br />raw coal is then transferred to a heavy media coal preparation plant where <br />it is sized and gravity separation methods are utilized to remove mineral <br />materials from the coal. Resulting coal products are dried, and <br />transferred to coal stockpiles. EFCI maintains two (2) separate <br />• stockpiles, a stoker coal and a clean coal stockpile. Coal from the <br />stoker coal stockpile is loaded into rear dump trucks for delivery in the <br />local area. Coal from the larger clean coal stockpile is loaded through <br />a reclaim tunoel'into conventional tractor/trailer units which transport <br />2.05-4 <br />
