【正文】 I 摘 要 本設(shè)計礦井為雞西礦業(yè)集團 張新 煤礦 ，一共有 3 層可采煤層，分別為 6B、 1， 煤層總厚度為 。 全區(qū)走向長 5500m， 傾向 2170 m,面積為 。 煤層工業(yè)牌號為 1/3焦煤，設(shè)計井田的可采儲量 ，設(shè)計服務(wù)年限為 56a。 本礦井設(shè)計采用以雙立井開拓，劃分為兩個水平， 共 六 個 采區(qū)，雙翼開采，兩個工作面達產(chǎn) 。大巷運輸采用 10 噸架線式電機車牽引，3 噸底卸式礦車運輸 。 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 , 頂板處理方法為全部跨落 法。 關(guān)鍵詞： 礦井設(shè)計 立井開拓 走向長壁采煤法 全套圖紙，加 153893706 II Abstract This design mine pit opens the Zhangxin coal mine mine pit design for Jixi Mining industry mine seam altogether has so me 3 may mine coal , respectively is 7, 6 B, 1,The coal seam total thickness is entire area moves tow ards long 5500m, favors 2170m, the area is square coal seam industry trademark is 1/3 coking coal, design w ell field recoverable resources , the design service life is in 56a. This mine pit design the double vertical shaft development, the division has two levels, altogether 6 pick the area, biplane wing mining, tw o w orking surfaces reach produce. The big lane transportation uses 10 ton wire laying type electric lootive hauling, 3 ton bottomdump mine car transportation, the mining coal method for moves towards the long wall mining coal law. The mining coal craft the synthesis mechanization mining coal roof processing method all cross falls the law. Key word: The mine pit design vertical shaft development moves towards the long wall to pick I 目 錄 摘 要 ..................................................................................................
