【正文】 I 摘 要 本 設(shè)計(jì)礦井為雞西礦業(yè)集團(tuán)張新煤 礦新井設(shè)計(jì)，設(shè)計(jì)生產(chǎn)能力為 ，服務(wù)年限 61a。井田內(nèi)共劃分為 2個(gè)水平開采，共有 7下 、 6A、 2共 3層可采煤層 ,井田平均走向長(zhǎng)度為 ，平均斜長(zhǎng)度為 ，煤層平均傾角 20176。 左右，屬傾緩斜煤層，采用雙立井開拓。 由于 該井田煤層屬緩 傾斜煤層 ， 三層煤間距 25m，整個(gè)礦井劃分為 6 個(gè)采區(qū)，經(jīng)過多方面經(jīng)濟(jì)技術(shù)比較， 決定本井田內(nèi)采用 走 向長(zhǎng)壁后退式采煤法進(jìn)行開采 ,工作面采用綜合機(jī)械化開采。 本設(shè)計(jì)礦井采用雙立井開拓方式 式， 中央邊界 式通風(fēng)。 關(guān)鍵詞 ： 走 向長(zhǎng)壁后退式開采； 礦井設(shè)計(jì)； 綜合機(jī)械化 開采；技術(shù)比較 煤層間距 全套圖紙，加 153893706 II Abstract This mine is designed for the zhangxin of jixi Coal Mining design production ability is Mt/a,service time limits mine is divided to two levels totally,there are 7下 、 6A、 2three layers in the mine that can be mined .The alignment of the mine grows , the tilt length is ahout and the average of the coal seam is 21176。or so,It is belongs to inclined coal seam. Because of ti is blongs to incline coal seam and there are only 25 metres .the whole mine is divided into six mining ares .through the econgic and technical paring ,the mine is decided to take the longwall working of alignment growing,the working place take the mining technology of the fully mechanized. This mine take the double wells to expand,It takes the central border to Ventilate. Keywords ： The longwall working of alignment growing； The mine of desigin； The mining technology of the fully mechanized； The technical parison；The distance of seam.
