采礦工程畢業設計論文-雞西礦業集團平崗煤礦12mta新井設計(已修改)

　

【正文】 I 摘 要 此次 設計 的 是 雞西 礦業集團公司 平崗煤礦 ， 總 共有 3層可采煤層， 它們 分別為 3 3 38， 煤層總厚度為 m， 煤層工業牌號為 1/3 焦煤 。井田 走向長度平均為 5839 m，傾向長度平均為 2876 m，煤層平均傾角為 19176。， 設計井田的可采儲量 為 ，設計服務年限為。 本設計礦井采用雙立井的開拓方式， 劃分為 2 個水平， 18 個采區。兩個工作面達產，達產時采區個數為 兩 個。 33層單獨開采， 3 38層集中開采。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，采煤工藝為高檔普采采煤工藝。 頂板處理方法為全部 垮 落法。 年工作日為 330 天，采用“ 四 — 六 ”式工作制，工作面長為 190m，每刀進度為 ，每日割 6 刀。提升設備為主井采用箕斗提升，副井采用罐籠提升。 關鍵詞 : 礦井設計 集中大巷 走向長壁采煤法 全套圖紙，加 153893706 II III Abstract This design is Mt / a new mine design of the Jixi Mining Group Pinggang mine. There are three layers that can adopt the coal seam. They are the 33, 35, 38. Total coal thickness is m. Coal industry brands is 1 / 3 average strike length of the mine is 5,839 m. The average tendency length of the mine is 5,839 m. The average inclination of the mine is 19 176。. Recoverable reserves of the mine design is Mt. Design service life is . The design of mine pioneering ways is doubleshaft. It is divided into two levels and 18 mining area. Two work faces reaches to the produce,and mining area of reaching to the produce is two .33 layer is adopted layer and 38 layer are adopted together. The big lane conveyance adopts 10 t a line type electrical engineering cars that leads 3 t bottom unload type mineral cars. Mining method is longwall mining method . Mining technology is highgrade general mining coal technology. Roof approach is the entire crossloading method. Working days is 330 days every year. Work system us foursix work system. The length of working face is 190 m. Each knife progress is m,and there are 6 times one main well adopts Ji Dou promote,and vicewell adopts bottle of the cage promote. Key words:Mine design Concentrate big lane Longwall mining method IV 目 錄 摘 要 ........................................................................................................................
