<br />• <br />2.05.3(1) <br />mine site. Paining will be carried on according to t!:e rules <br />and regulations enforced by PiSt!A and the Colorado Division of <br />P;fines. <br />A five entry system, the #1 North :fains, was originally designed <br />for the Red Canyon #1 trine with a heading on an azimuth of <br />- approximately 330 degrees. T.ahen Grand t•;esa Coal acquired the mine <br />in 1978, the location of the #1 Mains was dictated by the old mine <br />_ and the property boundary. Refer to the PSine Plan ltap, 2.05.3(1)-1, <br />the existing workings with the original Mains are shown cross- <br />hatched. these entries were continued on this azimuth until they <br />lined up with projections north between the old wor'.~ings and the <br />property boundary. The entry and crosscut centers are EO feet by <br />80 feet for the first 800 feet nor t:: in the #'_ tlains. The planned <br />• entry and crosscut widths will average 19 feet throuyhoLt th.e mine.' <br />--~ Once past the old workings, the Plains turn north and mining continues <br />on 60 foot entry and 80 foot crosscut centers. At this point, past <br />the old workings, another intake and another return was added on <br />the right side. The entries are numbered from left to right. In <br />the #1 north Plains the entries are #1 and #2 - return, =3 - belt, <br />#4 and #5 - intake, #6 - intake and #7 - return, The #1 north :aains <br />will be extended as far north as rederal leases are available. <br />Just below the north side of the SS 1!; NE; Section 12, a set of six <br />_ entries has been driven to the west, the #1 fNest Submains. The <br />location of the #1 [lest Submains is dictated by ownershia and t:ie <br />subcrop. The #1 [9est Submains were positioned as far no~th as <br />possible to reduce the hydrologic effect near the subcrop. In <br />Piarch 1981 while mining near crosscut 14+00 roof conditions <br />- started deteriorating in the #1 47est Submains. Permission was <br />granted by the Division to drill Ce-81-1 and Ce-B1-2 near [•:a rd <br />- Creek to identify any potential affect of the creel: on the ~~ining <br />• _. <br />REVISED 2-12-82 p~ <br />
