采礦工程畢業設計論文-雞西礦業集團盛和煤礦18mta新井設計(已修改)

　

【正文】 I 摘 要 本設計礦井為雞西 礦業集團盛和 煤礦 。 本 礦區內有 五 層 可采 煤 層， 分別為 1 2 34 48和 54均為全 區可采 ，平均總厚度 。走向長度 6500m,傾向長度 3500m,煤層平均傾角 20176。 ,視密度 ,煤層工業牌號為 1/3 焦煤，礦井涌水量一般為 ，最大涌水量為 140m3/h,設計井田的 工業儲量為 ,可采儲量 ，服務年限為 66a，本礦井設計采用 斜 井方案開拓，劃分三個水平， 八個采區，一水平可回采 第 一、二、三 采區， 采用 集中上山 布置， 走向長壁 后退式 采煤法采煤，綜合機械化回采工藝。 礦井的年工作 日 為 330d，采用 “四、六” 工作制，凈提升時間為 16h。 礦井的主 斜 井采用 波紋擋邊膠帶 輸送機提升 ，副 斜 井采用 串車提升 ,大巷采用 14t 架線式電機車牽引 3t 底卸式礦車運輸 。 通風方式為 分區 抽出式 通風。 關鍵詞 ：斜井 可采儲量 分區 抽出式 走向長壁 后退式 全套圖紙，加 153893706 II Abstract The new well designs Mt/a designing that the shaft is that Ji Xi City Corp. of mining industry holds the sum coal mine originally. The earth39。s surface is the closed country. The basalt covers western part , the physical feature of a place is slightly high, moist area of temperate zone , category continental are many wind the climate in the place. This mining area inner has a five layer of coal , is 18respectively tier,23tier, 342tier, 48tier, meters of 54layer of satisfy area but the spirit , average general thickness. The trend length inclines to 3500 meters of length 6500 meters,average 1923 degree of coal seam dip angle , unit weight m3, the coal seam industry shop sign is 1/3 charred coal , the shaft pours being m3/h like the water yield , the maximum pours the water yield is 140 m3/h, Mt designing the wellfield workable reserves, The level opening up , three dividing , eight mining area the be 66 , this shaft of length of service is designed adopt the inclined shaft scheme, one level but backstoping one , two , three mining area, adopt go up the hill all together arranging, the long unitary trend wall coal mining follows cut coal , synthetical machinized backstoping handicraft. The shaft host inclined shaft adopt big dip angles to transport machine being advanced , subsidiary inclined shaft adopts to string vehicle lifting III together, big alleys adopt dyadic electromobile of 14 tons of stringing to drag 3 tons of dropbottom car transportation , The way being ventilated is that the subarea draws out the dyadic ventilation. Key words: Inclined shaft Workable reserves The subarea draws out style The unitary trend grows wall IV 目 錄 摘 要 .......................................................................................................................
