The purpose of the MR is to <br />provide for an additional two (2) angle boreholes. One additional angle borehole is to be located at each of <br />two (2) approved and in place gob vent borehole (GVB) vertical borehole sites. These in place borehole sites <br />are located on lands managed by the USES. <br />Proposed boreholes: Panel 16: 16-07D and 16-08B. <br />Due to ground control issues, MSHA required Oxbow to conduct a mid-panel long wall move. As a result, <br />two of the in place GVB's 16-07 and 16-07B were bypassed and rendered non-effective to vent methane. <br />Because these two existing boreholes are not able to function as designed, the handling of mine methane <br />entering the post move mining areas has become more of a problem. These two proposed boreholes should <br />help to provide relief for the problem. <br />We are also including an updated Exhibit 2.04-E3, Geologic Information, Item 9 - Methane Drainage Well <br />Information and an updated Map 2.05-M1, Sheet 6 of 6, General Facilities Gobvent Boreholes (submitted <br />later under separate cover). <br />Please contact me at (970) 929-5806 should you have questions or require further information. <br />Sincerely, <br />J es A.
