~~ _~ ~ ~ TRAPPER DINING INC. February 13, 1987 [~E~~I~ED Mr. Gregg Squire FEB 271987 Colorado Mined Land Reclamation Division 423 Centennial Building MINEDI.AND 1313 Sherman street ~ECIAMATION DIVISION Denver, CO 80203 Dear Gregg: Trapper Mining Inc. is requesting a permit revision to our mining and reclamation permit to prevent the possible loss of surface mineable coal reserves in the Colt and Browning pit areas in the vicinity of Empire Energy's underground mining. IC was learned late in 1986 that Empire Energy will conduct underground long wall mining operations under portions of, ur in close proximity to, Trapper Mine's surface mineable reserves starting in approximately 1992. In order to prevent possible loss of Trapper's surface reserves, Trapper must start topsoil removal and conduct blasting operations in this area in 1987. If surface mining activities are not initiated in 1987, then either under- ground mineable or surface mineable coal reserves could eventually be lost. Empire's long wall operation will progress a[ a Easter rate than possible for Trapper's surface operations. Thus, Trapper must enter the area and have completed the extraction of surface mineable coal reserves cell in advance of Empire's operations. If surface operations are not completed in a timely manner, then surface blasting operations could result in unsafe conditions for the long wall operation and possible loss of these reserves to Empire. However, if surEac'e mining were to follow the long wall underground operation, Trapper could suffer loss of substantial surface mineable coal reserves. Expected subsidence from long wall mining has the potential to fracture [he overlying strata and surface mineable coal seams. The result of the fractur- ing could prohibit successful overburden drill and blast operations and con- taminate surface recoverable coal reserves. Thus, Trapper deems i[ in our best interests [o mine the surface mineable coal reserves prior to Empire's long wall underground mining. Undec the terms of our existing mining and reclamation permit, the Division has previously determined that adequate baseline information exists [u con- duct mining and reclamation operations in the Cult and proposed Browning pit areas. Further, Colt pit was active previously and will be reactivated under this cevision. Enclosed with this permit revision are plans adequate to address the first phase of the proposed activity, specifically, road construction, sediment and drainage control, topsoil handling, blasting cont.
