Chapter II <br /> These are controlling factors of actual coal production which have proven difficult to <br /> anticipate. As a result, Mid-Continent has found it necessary to be highly adaptable <br /> in all aspects of the Coal Basin operations. <br /> Coal produced from the first year of production to the last full year of production <br /> prior to submittal of the application (1956 through 1986) totals 19,332,146 tons, an <br /> average of 644,404 tons per year. Production over the 30-year period for each of <br /> the two seams being mined totals 14,468,121 tons of coal from the lower B-bed <br /> seam; 4,864,625 million tons of coal from the upper, M-bed seam. <br /> Modernization of the mine will allow for greater productivity and higher tonnages if <br /> market conditions are such that there is a demand for more coal production. From <br /> 1980-1986, the average annual production for the Coal Basin operation totalled <br /> 815,121 tons, which represents an increase over the 30-year average, although <br /> demand for coal has been constrained due to a downturn in the steel industry. <br /> During the first three quarters of 1987, the Coal Basin operations produced a total of <br /> 604,932 tons of coal, including 57,398 tons from the B-bed and 547,534 tons from <br /> the M-bed. <br /> 2. Operation Description <br /> a. Surface Operations Related to <br /> Underground Mining. <br /> The permit area of the Coal Basin operations, including disturbed area, and land <br /> above the underground workings, including past and projected mining, totals <br /> 11,386 acres. <br /> The permit area is on both sides of the Huntsman Ridge. <br /> Surface facilities and mine entries are located on the east side of the ridge within <br /> Coal Basin. The basin extends over an area of approximately 26 square miles <br /> (Exhibit II-A-1). <br /> Disturbed area within the permit area totals 333 acres. <br /> Areas of surface disturbance include the Adit/Rock Tunnel yard, main entry portals <br /> and ventilation fans, hoists, loading bins, roads, preparation plant facilities, coal <br /> processing waste disposal areas, solid waste disposal areas, water control <br /> structures, offices, power transmission lines, methane pipeline, oil and gas storage, <br /> powder magazines, parking lot facilities, other miscellaneous structures.
