Mine design recoverable reserves of Mt, design service life of 51 years. This mine design used the doubleshaft development, divided into two levels, six mining area. Used the singlewing exploitation every mining area, the two face up to the middle, two face ready, there are two Mining Areas when production, all seams are individual mining, roadway transport used 10 tons of FLine traction motor vehicles, three tons dump cars transport, Section transport belt conveyors used in horizontal transport, Face scraper transport planes . Mining method for longwall mining, the mining technology to ordinary mechanized mining technique. Working face hydraulic prop and hinged beam supporting the roof all the way to handle cross loading method. Working days, 330 days, the daily up grade 16 hours. Key words: mine design shaft pioneering longwall mining merhod III 目 錄 摘 要 .................................................................................................
