【正文】 ine is about in all. The proved reserves of the minefield are million tons. The recoverable reserves are tons. The designed productive capacity is million tons percent year, and the service life of the mine is 63 years. The normal flow of the mine is 75 m3 percent hour and the max flow of the mine is 120 m3 percent hour. The mineral well gas gushes the deal higher, for high gas mineral well. The well farmland is a single level in an inclined well to expand. The working system “foursix” is used in the Sehe mine. It produced This design includes five chapters: outline of the mine field geology。5. the safety operation of the mine. Special subject parts of topics is Forecasting and Identifying of coal and gas outburst. Translation part of main contentses, English topic is: Mitigation of Methane Emissions from Coal Mine Ventilation Air 目 錄 一般部分 1礦區(qū)概述及井田地質(zhì)特征
