• Tract Delineation Report - 2003 The MCC WFT LBA Paqe 4 Mining at the West Elk mine, 1 to 3 miles to the S-S W of the tract, has encountered some rolls in the coal seam as well as techtonic displacement faults. Rock spazs have also been found present in the coal running at about a 30E angle to the strike of the structure. The WFT is expected to have four fault zones about evenly spaced from north to south. The zones are labeled on the West Elk Mine maps from north to south as: Un-named; Oliver #2; B East Mains; and 14HG. These zones have exhibited themselves in the current mine workings as everything from fracture zones to having several blades with vertical offsets ranging from a fraction of a foot to 21 feet. Heavy inflow of both methane and warm water can occur in these zones when they are contacted by development mining and extra ground control devices are necessary to counteract weaknesses due to fractured roof and ribs. The fault zone contact location will usually experience heavy initial flow of both methane and water that eventually subsides, but must always be anticipated and alleviated. Methods now used to alleviate the heavy flows (and deal with the residual flows) are expected to be employed on the WFT wherever they become necessary. Mining through the zones on development or with the longwall requires extra finesse so that the safety of men and equipment is maintained and the product~mined is the best quality possible. V. Coal Data The coal is ranked high-volatile B. The proximate as received Analysis for the B • seams comes from the drill hole data of three holes influencing the area of the WF, and is as follows: B seam Ash 9.78 % Sulphur 0.61% Water 6.56% BTU 12,368 Because dilution is expected (due to the M2 parting) in the eastern extent of the longwall blocks, the nm-of--mine quality from the WF is expected to be as follows: B seam Ash 12.20 % Sulphur 0.60% Water 6.52% BTU 12,015 Although this product is not up to contract specifications of less than 10.5% ash, there are some spot mazkets that will buy it, and the rest can be blended down with better quality coal to meet contract specifications. This option is better for MCC and the government rather than bypassing it. Coal Quantity The following coal quantity determinations were calculated by the BLM mining engineer (Uncompahgre Field Office) in September 2003, as part of the BLM Tract Delineation report for the WFT application. Based on three different azeas of ash concentration (M2 influence) for a projected longwall development and mining plan that takes advantage of the most encouraging easterly trend of the M2 parting, the following B seam reserves were calculated (Table at the top of the next page):
