采礦工程畢業設計論文-雞西礦業集團平崗煤礦150mta新井設計(已修改)

　

【正文】 I 摘 要 本設計礦井為雞西礦 業集團 平崗煤礦 。 此礦區內有 三層煤全區可采 ，平均總厚度 米。煤層工業牌號為 1/3 焦煤， 井田的可采儲量 為 ，服務年限為 年 。 本礦井設計 開拓方案為雙斜井開拓方案， 劃分二個水平， 一 個工作面達產。采用分層布置，大巷采用 10噸架線式電機車牽引 3 噸底卸式礦車運輸， 單一走向長壁采煤法采煤，綜合機械化回采工藝。通風方式為分區對角式通風。 關鍵詞 可采儲量 分區對角式 單一走向長壁 全套圖紙，加 153893706 II Abstract This design of the mine in Pinggang of Jixi Mining Company Mine is a Mt/a new mine design. This mini have three recoverable coal region, the average total thickness is meters. Coal industry brands for 1/3 coke, the workable reserves of this mine is , the length of service is mine design exploit project is double inclined shaft sinking with two level of division, face up to a production. Stratified settings, the main roadway using 10 tons of overhead line electric traction 3 tons inclined bottom car, single long wall mining method along coal mining method is totally mechanized coal mining. Ventilation of the design is diagonal ventilation. Keywords： workable reserves diagonal ventilation single long wall mining method along strike 1 目錄 摘 要 .......................................................................................................................
