采礦工程畢業設計論文-雞西礦業集團新發煤礦12mta新井設計[2](已修改)

　

【正文】 I 摘 要 本設計礦井為雞西礦務局新發煤礦 ，一共有 3 層可采煤層，分別為 2 2 4，煤層總厚度為 。煤層工業牌號為 1/3 焦煤，設計井田的可采儲量 ，設計服務年限為 。 本礦井設計采用以雙立井開拓，劃分為兩個水平，共十八個采區，雙翼開采，兩個工作面達產， 2 2 4分層 開采。集中大巷采用 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 普通 機械化采煤工藝。頂板處理方法為全部跨落法。 關鍵詞 礦井設計 立 井開拓 走向長壁采煤法 全套圖紙，加 153893706 II Abstract This design mine is opened by the Xinfa coal mine mine design for Jixi Mining bureau, This mine altogether has 3 level that can adopt coal seam， w hich is 2 2 4 , The total thickness of coal seam is coal seam industry quality is 1/3 of coking coal, design well field recover resources , the d esign length of service is years. This design mine uses the double vertical shaft development, divided as tw o mining levels, altogether 18 districts, biplane wing mining, two w orking face reach to produce, 2 2 4 consociation gatheri ng main roadway uses 10 ton wire laying type electric loco motive hauling, 3 ton dropbottom mine car transportation, the mining coal method is longwall coal mining method, the mining coal craft is the mechanized mining roof processing method is all cross falls the law. Key word Mine design Vertical shaft development Longwall coal mining method III 目 錄 摘 要 .....................................................................................
