【正文】 I 摘 要 本設計礦井為鶴崗礦業(yè)集團南山礦 ，共有 3 層可采煤層，可采煤層厚度從上到下依次為 、 、 15m，煤層的平均傾角為176。， 煤層的工業(yè)牌號為 1/3 焦煤。設計井田工業(yè)儲量 ，可采儲量 ，服務年限 。 本設計礦井采用雙立井開拓方式，井筒位置選擇在井田儲量中心的西部，劃分兩個開采水平。大巷布置方式采用集中大巷布置，大巷運輸方式采用 8t 蓄電池電機車牽引 固定礦車運輸。采煤方法為走向長壁采煤法，采煤工藝為綜合機械化放頂煤開采，采空 區(qū)處理方法為全部垮落法。 主井采用一對 12t 箕斗提升，副井采用一對三噸雙層單車罐籠不平衡提升。 礦井通風方式為兩翼抽出式，其中北翼風井選擇在北一、北二兩個采區(qū)的上山之間，南翼風井選擇在南一、南二兩個采區(qū)的上山之間。 礦井的排水方式為分區(qū)式排水，其中北一、南一采區(qū)使用一個排水系統(tǒng)，北二、南二采區(qū)分別使用一個排水系統(tǒng)。 關鍵詞 ：雙立井；集中大巷；走向長壁；放頂煤開采 全套圖紙，加 153893706 II Abstract This is a new design of mining Group, which has three workable coal seams. Thickness of coal seam is , , 15m from top to bottom. Slope angle of coal seam is 176。 , industry card of which is 1/3 coking coal. Industry quantity of the mining filed is Mt, and the workable reserves is Mt, service life is . The mine design uses the double vertical shaft development. Shaft position is selected in the west of the storage center. The mine is divided into 2 levels, dopting concentrated main lane decoration。 the main lane adopts 10t haulage motor to lead the fix car. Coal mining method is strike longwall working, and conventional machinery breaking mining. The roof is caving method roof control. The hoist uses the 12t multiropes to lift. The chippy hoist is a pair of 3t double layer cage. Mine ventilation is doublevane drawing out north air shaft is established between two distract raise of north and , and the south is between south and . Draining method is zone patterns. The north and south use one draining system, and the north and south use two draining systems. Key words: Double Vertical Shaft。 Concentrated Main Lane。 StrikeLongwall Working。 Breaking Mining III 目 錄 摘 要 .........................................................................................................................
