We are <br />therefore requesting an additional supply of coal per a technical <br />revision that would allow mining to continue beyond the end of January <br />1982 and through the end of July 1982, which would allow for additional <br />responses from Blue Ribbon, your final review and issuance of written <br />findings, and proper notification for the permit application. <br />An update excerpt from Exhibit C is attached which shows the mine <br />layout for the Blue Ribbon Mine. I have shaded on this exhibit the <br />areas which will be mined during February through July 1982. You will <br />note that pillar extraction will continue as approved by MLRD. The <br />October 1981 technical revision approval and my letter of October 29, <br />1981, describe our intent for mining plan for this extended period <br />except for now outdated projection period. <br />An accurate six month projection is again difficult because the <br />mining rate will be dependent on the secondary mining recovery. Blue <br />Ribbon Coal proposes the following: <br />1. Complete secondary mining in the area between the 5 East and <br />4 East Rooms. Much of the secondary mining in this area will <br />be completed in January 1982. This pillar recovery concept <br />is discussed briefly in the permit application. <br />2. Develop 3 East Rooms now projected as 100' x 100' C.L. <br />3. Recover the coal between 4 East Rooms and 3 East Rooms. <br />4. Start development of 2 East Rooms. Steps 1 to 4 would <br />then repeat. <br />Mining should be completed in 1st Nor[h, the general area between <br />5 East Rooms and 1 East Rooms and adjacent chain pillars in June 1982. <br />The remainder of June and July will be spent developing 2nd North. The <br />projection is now a 3 entry 100 foot centers development. <br />
