采礦工程畢業(yè)設計論文-雞西礦業(yè)集團張新煤礦09mta新井設計[4](已修改)

　

【正文】 I 摘 要 本設計礦井為雞西礦業(yè)集團張新煤礦 ，一共有 3 層可采煤層，分別為 6B、 2， 煤層總厚度為 米。煤層工業(yè)牌號為 1/3 焦煤，全區(qū)走向長 5900M，寬 2150M,面積為 平方 KM。設計井田的可采儲量 ，設計服務年限為 51 年。 本礦井設計采用雙立井開拓，劃分為兩個水平，六個采區(qū)。每個采區(qū)為單翼開采，兩個工作面達產，兩個工作面準備，達產時采區(qū)個數為兩個，煤層全部單獨開采，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，區(qū)段運輸平巷采用帶式輸 送機運輸，工作面采用刮板運輸機運輸。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。工作面采用單體液壓支柱和鉸接頂梁支護，頂板處理方法為全部跨落法。年工作日 330 天，每日凈提升 16小時。 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 The design is about a in the JiXi Mining Group. there are three layers coal seam in total, 8, 6B, 2 respectively, the total thickness of the seam is meters. the industry of the coal is 1/3 coke, the long of region tow ard is 5900M, the wide is 2150 M, the area is square KM. Mine design recoverable reserves of Mt, design service life of 51 years. This mine design used the doubleshaft development, divided into two levels, six mining area. Used the singlewing exploitation every mining area, the two face up to the middle, two face ready, there are two Mining Areas when production, all seams are individual mining, roadway transport used 10 tons of FLine traction motor vehicles, three tons dump cars transport, Section transport belt conveyors used in horizontal transport, Face scraper transport planes . Mining method for longwall mining, the mining technology to ordinary mechanized mining technique. Working face hydraulic prop and hinged beam supporting the roof all the way to handle cross loading method. Working days, 330 days, the daily up grade 16 hours. Key words: mine design shaft pioneering longwall mining merhod III 目 錄 摘 要 .................................................................................................
