【正文】 I 摘 要 該設計為呼倫貝爾市大雁礦業(yè)集團公司大雁三礦的新井設計，設計生產能力為，服務年限 53a。該井田平均走向長 ，平均傾斜長 ，煤層平均傾角16176。，屬緩傾斜煤層。井田內共有 4個可采煤層，分別為 1 2 3 36煤層，煤層總厚度為 。設計井田內煤種為褐煤，可采儲量 。設計采用雙斜井的開拓方式，將該井田劃分為一個開采水平，兩個采區(qū)，實行上、下山開采。每個采區(qū)為雙翼開采，一個工作面達產，達產時采區(qū)個數(shù)為一個，采用集中布置方式開采。大巷運輸采用 10t架 線式電機車牽引 3t底卸式礦車運輸，采用的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。頂板處理方法為全部跨落法。 關鍵詞 ： 斜井開拓 聯(lián)合開采 走向長壁 全套圖紙，加 153893706 II Abstract This design is for Dayan Mining Group CO.,CTD the third mine’s new mine planning of Inner Mongolia . Its productivity is ,and its service time limit is planned to be as long as 53 mine is about kilometers long and kilometers wide, average rake angle in coal is 16 176。.There are totally 4 layers can adopt the coal seam,includeing 1 2 3 36,and the total thickness in the coal seam is cole in the mine is brown cole, design the mine can adopt to keep the Mt of mine is planned To take the way of double subshaft mine development,and divided the mine to a whole horizontally, two one adopts area as a mines, one works reaches to produce, reaching to produce adopt area piece as fore layers concentrates to big lane conveyance adopts 10 ton a line type electrical engineering cars lead 3 ton bottom unload type mineral cars transport, adopting of adopt coal method as the alignment the long wall adopt the coal method, adopting coal craft as to synthesize the mechanization adopt the coal plank handles method as to across to fall the method all. Keywords: slope development Unites to development alignment long wall III 目 錄 摘要 .....................................................................................................................I Abstract...............................................................................................................
