【正文】 I 摘 要 本設(shè)計(jì)礦井為 雙鴨山 礦業(yè)集團(tuán) 東榮 三礦 ，共有 5層可采煤層，厚度 。煤層工業(yè)牌號(hào)為肥氣煤，設(shè)計(jì)井田的可采儲(chǔ)量，服務(wù)年限為 80a ，本礦井設(shè)計(jì)采用雙立井開(kāi)拓 方案 ， 16t 箕斗提升， 劃分兩個(gè)水平， 一 個(gè)工作面達(dá)產(chǎn)。采用 分組 集中大巷布置，大巷采用 10t架線式電機(jī)車(chē)牽引 5t底卸式礦車(chē)運(yùn)輸， 設(shè)計(jì)采區(qū)為 中二 采區(qū)，生產(chǎn)能力，服務(wù)年限為 ， 采煤方法為 走向 長(zhǎng)壁 后退 采煤法，采煤工藝為綜合機(jī)械化采煤工藝。 關(guān)鍵詞 立井 開(kāi)拓 采煤工藝 集中大巷 走向長(zhǎng)壁 采 煤法 全套圖紙，加 153893706 II Abstract This design mineral mine as the shuangyashan mineral industry grou the third Dongrong mineral , having totally 5 layers can adopt the coal seam, thickness coal seam industry card number is a fatty spirit coal, designing the mine recoverable reserves can adopt to keep deal as Mt, the length of time is80years, this mineral mine design adoption double vertical shaft development the project, the promotes of 16t, dividing the line two levels,one working face reaches to big lane in concentration in adoption arranges, the big lane adopts 10t a line type electrical engineering cars lead 5t bottom unload type mineral cars transport, designing to adopt area as the cocent on adopting the area, produce ability as Mt/ a, length of service time limit for years, adopt coal method as to Longwall coal mining method, adopting coal winning echnology as to synthesize the mechanization adopts the coal craft. Key words: vertical shaft development mining technology gathering main roadway Longwall coal mining method III 目 錄 摘 要 ......................................................................................................................
