采礦工程畢業設計論文-雙鴨山礦業集團東榮三礦30mta新井設計(已修改)

　

【正文】 I 摘 要 本設計為雙鴨山礦業集團東榮三礦 。此礦區內有 5層煤全區可采， 且其均為厚煤層， 煤層平均厚度為 ，走向長度為 8km，傾向長度 為 ，煤層平均傾角為 12176。 。 本井田內 可采儲量為 ，服務年限 為 78a。 煤的工業牌號為肥氣煤 。本設計采用立井多 水平開拓， 聯合開采 和集中大巷布置，大巷采用 10t架線式電機車牽引 5t底卸式礦車運輸。采煤方法為走向長壁采煤法，采煤工藝為綜合機械化采煤，采空區處理方法為全部垮落法。 關鍵詞 ： 井田開拓 開采 水平 走向長壁 采煤 工藝 全套圖紙，加 153893706 II Abstract This new mine is designed for ShangyaShan mineral industry group limited liability pany the third coal mine,which capacity is , and the average thickness in coal seam is meters. It is 8,000 meters along the longwall,and is 3,100 meters along the inclined longwall, the average rake angle is degree in this coal whole of recoverable reserves is million ton， which can be serviced 78 of the coal seams are thick seam, and the indrstry card of the coal is fatty gas design two mining levels to develop all coal seams, adopting the single lamella arrange the sum the cent set concentrates the main roadway arranges, the main roadway adopts 10 ton a line type electrical engineering cars lead ton bed unload type car, pit tub mining technology is along the longwall coal mining, and the mining texhnology is fullmechanized,the gob waste treats method is plete caving method. Key Words： vertical shaft development mining Level longwall coal minning coal mining technology III 目 錄 摘要 ..............................................................................................................................
