2-28 <br />2.2.1 Buildings and Other Facilities <br />• <br />MINE SITE <br />One office trailer is located on the mine bench. The 3MV substation is <br />supported by six concrete footers which are two feet wide. There is a high <br />voltage overhead power line that extends from the existing Grand Valley Power <br />mainline to the portal area substation. The power line is approximately 2200 feet <br />long. The 40' X 40' shop building has been constructed with a concrete floor. A <br />2,000 gallon fuel storage tank has been nested inside a cathodically protected <br />4,000 gallon tank as a secondary containment. <br />The conveyor belt exits the mine and discharges into a crushing and <br />•~ screening facility. This facility is comprised of a 7' X 16' double deck screen and <br />a triple roll crusher. The sized product from the crushing and screening facility is <br />conveyed to a coal stockpile by a 120-foot 36-inch radial stacker belt. The radial <br />stacker wheels are supported by a retaining wall and concrete runway. The <br />foundation for the crushing and screening facility is a concrete pad with wing <br />walls. Figure 2.2-2 shows the location of buildings and other facilities which area <br />listed in Table 2.1-1. Figure 2.2-6 shows buildings and other facilities located in <br />the vicinity of the portal bench. During 1989, the Operator installed a bulk <br />rockdust bin and a concrete footer for its support. <br />The 48-inch mine belt is supported by a channel/truss frame and extends <br />approximately 24 feet outby the portal where it discharges onto the screen deck. <br />A 40-foot long 48-inch conveyor collects sized coal from the screen and crusher <br />•~ and conveys the product to the stacking belt. <br />McClave Volume 1 03/06 <br />
