BOWIE RESOURCES LIMITED Bowie No. 2 Mine Mine Portal Haul Road Certification The mine portal haul road traverses from old State Highway 133 to the mine bench. The road climbs approximately 800 vertical feet in about 9500 lineal feet. The original design of the road did not anticipate its use as the main coal haul route. A coal conveyor was to be constructed from the mine bench to a truck loadout which was to be located adjacent to old State Highway 133. Bowie Resources Limited decided to delay construction of the coal conveyor and haul all of the coal produced from the Bowie No. 2 Mine down the mine portal haul road. In accordance with Rule 4.03.1 (1)(d), this certification has been prepared to certify mine portal haul road has been constructed as designed and in accordance with the approved plan. The mine portal haul road was constructed beginning in May 1997 and was completed in October 1997. Compaction tests were taken and recorded by Maxim Technologies. Where compaction tests failed, the fill was reworked and compacted. L. Kirt Jewkes, under my supervision, was present during most of the construction. Mr. Jewkes and I (J. E. Stover, P.E.) have a wide variety experience in the design and construction of earth fill embankments. The permitted configuration of the haul road is a 20-foot wide roadway with an earth and rock safety berm on the outside slope and a drainage ditch on the inside. Haul roads were to be plated with four to six inches of gravel. Technical Revision No. 1 (TR- 01)revised the design of the haul roads to include a 20 to 24-foot wide roadway, an earth and rock safety berm or guardrail on the outside slope and a drainage ditch on the inside. Haul roads are to be plated with 10 to 20-inches of gravel surfacing. The main haul road from old State Highway 133 to the portal level will be paved. To the best of my knowledge and belief the mine portal haul road was constructed in accordance with the approved plan and meets the requirements of the Regulations of the Division of Minerals and Geology. In fact, the mine portal haul road was constructed to the requirements of TR-01 (not yet approved) which exceed the requirements of the currently approved plan. The mine portal haul road was plated with 10 to 20 inches of gravel surfacing and 6-inches of hot bituminous asphalt. The paved haul road has two 12-foot wide lanes and curve widening is provided on curves with a radius less than 180 feet. Guardrail will be instaldp$~f~t~q;the road during November 1977. ~ /o~P ,..F .: ;str o ~o~'; ~ 1%G,','yF'~ 0 /4~" ~ j ~~'Jam~s~' . toyer . D~ `'O.,oR E. No. 19230: •:~O~yAI ~~'~ ..~.
