采礦工程畢業設計論文-雞西礦業集團平崗煤礦18mta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礦的新井設計，共有 3 層可采煤層， 25 33 35 。 平均厚度 3. 8m。煤層工業牌號為 1/3 焦煤，設計井田的可采儲量，服務年限為 61a，本礦井設計采用雙立井方案開拓，劃分二個水平，兩個工作面達產。采用集中大巷布置，大巷采用 10t 架線式電機車牽引 3t 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工藝。 關鍵字 ： 礦井設計； 開拓 ； 水平 ； 走向長壁 全套圖紙，加 153893706 II Abstract This is a new design for has workable coal are 2 3 35.Total thicknes of coal seam is coal seam industry trademark is 1/3 coking mine field recoverable resources is This mine， s life is 61years. This mine pit design uses the double vertical shalt development the division as two working face can achieve The big lane transporation uses 3 tons Bottomdump mine cars to Mining method for longwall mining, coal mining technology for integrated mechanized mining technique. key words The mine pit design expands the level alignment long wall I 目錄 摘 要 ..........................................................................................................................
