~J <br />2.2.1 Buildings and Other Facilities <br />MINE SITE <br />One office trailer will be located on the mine bench. The 3MV substation is <br />supported by six concrete footers which are two feet wide. The 40' X 40' shop building <br />has been constructed with a concrete floor. Expansion of the building to 40' X 100' is <br />shown on Figure 2.2-2 and reclamation costs are included on Table 3.7-1. The 2,000 <br />gallon fuel storage tank has been nested inside a cathodically protected 4,000 gallon <br />tank as a secondary containment. <br />The conveyor belt exits the mine and discharges into a crushing and screening <br />facility. This facility is comprised of a 7' X 16' double deck screen and a triple roll <br />crusher. The sized product from the crushing and screening facility is conveyed to a <br />coal stockpile by a 120-foot 36-inch radial stacker belt. The radial stacker wheels are <br />supported by a retaining wall and concrete runway. The foundation for the crushing <br />and screening facility is a concrete pad with wing walls. Figure 2.2-2 shows the <br />• location of buildings and other facilities which area listed in Table 2.1-1. Figure 2.2-6 <br />shows buildings and other facilities located in the vicinity of the portal bench. During <br /> <br />1989, the Operator installed a bulk 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. A 40- <br />foot long 48-inch conveyor collects sized coal from the screen and crusher and <br />conveys the product to the stacking belt. <br />The operator may replace the existing metal portal arches with concrete portals. <br />The concrete portals will be approximately 30 feet long so backfill can be placed along <br />the length of the coal outcrop. The backfill will prevent further oxidation and sloughage <br />of the coal from under the overlying sandstone and resultant deterioration of the <br />z-za <br />formation. Concrete portals will also enhance protection for miners entering and exiting <br />the mine. The configuration of the portals are shown on Figure 2.2-2. Reclamation of <br />the concrete portals will involve breaking up the concrete and placing it into the mine <br />openings. Reclamation cost calculations are detailed in Table 3.7-1. <br />M`Clane <br />Volume 1 <br />12/99 <br />
