III IIIIIIIIIIIII III <br />January 28, 1987 <br />CERTIFIED P297324766 <br />Mr. Bill Holegate <br />Mine Safety and Health Administration <br />District 9 <br />P.O. Box 25367 <br />Denver, CO 80225 <br />Dear Bill: <br />FEa~~~% <br />N11NE0 ~~O~V1$1ON <br />~yEGtAMp,T1ON <br />In accordance with Colorado Surface Coal Mining Reclamation Act regulations <br />4.19 Protection of Underground Mining and 4.22 Concurrent Surface and Unde r <br />ground Mining, Trapper Mining Inc. is reaues[ing a variance to the 500-four <br />barrier, measured horizontally, [hat shall be maintained between surface and <br />un~ierg ro and mining a. [iv hies. To can ply with [he se regulations governing <br />variances to this rule, ioint approval must be granted by Colorado Mined Land <br />Reclamation Division (CMLRD) and by Aline Safety and Health Administration <br />( I•.S HA) . <br />Trapper Mining Inc. is applying for Che variance so that improved coal <br />resource recovery may be obtained from the area. It is estimated that the 75 <br />acres included within the 500-horizontal barrier contains 930,000 tuns of sur- <br />face mineable coal. The area for which the variance is requested is shown on <br />Map TR-32-1 for the 1987 C Pit Permit Revision, and on Map At-8 for the 1988 [o <br />]992 Permit Renewal submitted to the CMLRD. <br />*to st of the underground workings shown on these maps are abandoned room and <br />pillar mining areas for which an estimated 85% extraction was accomplished. <br />Ko currently-active headings fall within 500 horizontal feel of the planned <br />blasting area, although during the permit term [he possibility exists. <br />Due to the nature of the geolog}~ and the vertical separation of the two mining <br />operations, Trapper feels the health and safety of the underground miners will <br />not be compromised. To insure the safety of EYnpire Energy's Eagle No. 5 Mine <br />workers, blasting within [he 500-foot horizontal barrier area will be done <br />during Empire's shift changes when none of their workers are in the area. To <br />insure the safety of Empire ac [ivities, Trapper Mine will use a controlled <br />blasting schedule which will be coordinated with Empire Energy Corporation. <br />con[. <br />P.0 Box 187 <br />Crain.
