【正文】 I 摘 要 本設(shè)計礦井為七臺河 精煤 集團有限責任公司新建七 礦 計，共有 5 層可采煤層，煤層平均總厚度為 5m，煤層工業(yè)牌 號為 1/3 焦煤為主 。設(shè)計井田的可采儲量 Mt， 礦井 服務(wù)年限 為 。 本設(shè)計礦井采用雙立井開拓方式，劃分兩個開采水平。采用分組集中大巷布置，大巷采用 10t 蓄電池 式電機車牽引 底卸式礦車運輸，采煤方法為走向長壁采煤法，采煤工藝為 普通 機械化采煤工藝，采空區(qū)處理方法為全部垮落法。 主井采用多繩摩擦箕斗提升，副井采用剛性組合罐道罐籠提升。 關(guān)鍵詞 ： 開拓 。 開采 水 平 。 分組集中 。 走向長壁 全套圖紙，加 153893706 II Abstract This design mine pits for the Qitaihe refined coal group limited liability pany newly built seven ores , altogether has 5 to be possible to pick the coal bed, coal bed average total thickness is 5m, the coal bed industry trademark is 1/3 coking coal primarily. This design mine pits selects the double vertical shaft development method, divides two mining the grouping to concentrate the big lane arrangement, the big lane uses 10 ton accumulator cell type electric lootive to tow the bottomdump mine car transportation, the mining coal method for moves towards the long wall mining coal law, the mining coal craft for the ordinary mechanized mining coal craft, picks the depletion region processing method for to break down pletely falls the law. The main well uses the multiropes to rub the ore basket promotion, the vice well uses the rigid bination pot cage promotion. Key word: Development。 Mining level。 Grouping centralism。 Moves towards the long wall III 目錄 摘 要 .........................................................................................................................
