采礦工程畢業設計論文-雙鴨山礦業集團嶺東煤礦09mta新井設計(已修改)

　

【正文】 I 摘 要 本 次 設計新井為雙鴨山礦業集團嶺東煤礦 ，共有 3 層設計可采煤層，平均總厚度為 。設計 嶺東 井田的可采儲量為 ,服務年限為 ,劃分兩個水平開采。井田平均走向長 2500m，平均傾斜長 2020m，煤層平均傾角 12176。，屬于緩傾斜煤層。 嶺東煤礦 采用雙立井的開拓方式，分組集中大巷布置方式。共劃分八個采區，其中首采區為 1 個，達產工作面 1 個。 首 采區為北一 采區 ，大巷裝車式下部車場，綜合機械化采煤。年工作日為 330天，采用“三 八”式工作制，工作面長為 190m，每刀 截 深 為 ，每日割七刀。 主井采用 箕斗提升，副井采用罐籠提升。由于 嶺東 井田傾斜長度較長，且為緩傾斜煤層，以及煤層地質條件等因素影響，決定 井田內全部采用走向長壁開采。 關鍵詞 可采儲量 采煤工藝 走向長壁 全套圖紙，加 153893706 II Abstract The mine designing that the new mine is Shuang Ya Shan City mining industry Corp. Ling Dong coal mine new of Mt/a time designs capital, mon 3 layer of the m designing that average general thickness is tier may cut coal. Mt designing that Ling Dong minefield workable reserves is , the length of service is as, level dividing two exploit. The average trend of minefield grows 2500 ms , average incline is long 2020 ms, average dip angle of coal seam 1239。, belongs to the slow incline coal seam. The developing way , grouping that the Ling Dong coal mine adopt to shaft pair concentrate big alleys arranging way. Divide eight mining area together, head mining area among them is 1 , amounts to 1 product face. Mining area is the north one mining area, the car park , synthetical mechanization cut coal on big alley entrucking style lower part. The annual workday is 330 day , adopt the three , eight dyadic character of service, face often is 190 ms , every knife intercepts depths being that m, is everyday cut seven knives. The main shaft adopt skip lifting to fight against , the auxiliary shaft adopt a cage to be advanced. The length is longer since Ling Dong minefield tilts, and for slow incline coal seam, inner affecting , deciding minefield as mine as coal seam geology condition waits for a factor all adopt long trend wall coal III mining law exploit. Since my knowledge is limited, be short of the certain scene experience. A little problem appears on the meeting hard to avoid designing middle Key words recoverable reserves coalwinning technology Longwall coal mining I 目錄 摘要 ........................................................................................................
