i : ~_ - <br />1 -31 <br />Mining will begin in the SWJ4, NW/4 Section 34 and move into the <br />NW/4, NW/4 Section 34 and into the E/2, NE/4 Section 33. Mining as <br />practiced at the Sunlight Mine is simple and efficient. <br />The system consists of entering the "D" seam by way of a slope <br />' driven down the dip of the seam. The upper-most of these becomes a <br />haulage-way end fresh-air-intake, while the lower one becomes an <br />' exhaust-air-way. Rooms are driven up-the-dip from the upper entry. Coal <br />is drilled on the solid and shot, rolling to the bottom of the room by <br />' gravity. At the bottom, it is pulled through chutes into mine-cars on the <br />haulage level, trammed to the slope, dumped into the skip, hoisted to the <br />surface and discharged into the tipple. Roof-control is achieved by <br />' installation of posts on 4' centers. <br />When mining has reached the property limit, pillars are pulled on <br />the way back to the slope and the system is repeated at a lower level in <br />the slope. <br />Complete details of the operation of the system are provided under <br />2.05.3, along with appropriate maps. <br />2.05.3 Operation Plan - Permit Area <br />2.05.3 (1) and (2) Operation Description, Including Production Methods and <br />Equipment <br />' Previous Operations <br />' The Sunlight Mine was developed prior to 1910 by Colorado Fuel & <br />Iron in a search for reserves of metallurgical coal. When the coal was <br />' determined to be other than metallurgical, C.F. 6 I, abandoned the <br />property. Since that time, the property has had a series of <br />' owner-operators, the most recent of which were The Carbon King Corporation, <br />and the Fourmile Coal Company. <br /> <br />t <br />
