【正文】 I 摘 要 本設計礦井為雞西哈達煤礦 ，一共有 3 層可采煤層，分別為 2 36， 煤層總厚度為 6m。煤層工業(yè)牌號為 1/3 焦煤，設計井田的可采儲量 ，設計服務年限為 。 井田平均走向長度為，煤層平均傾角為 12176。，屬于緩傾斜煤層。 本礦井設計采用以立井為主的綜合開拓方式，劃分為兩個水平，八個帶區(qū)，兩個采區(qū)。本著“節(jié)約優(yōu)先，效率為本”的原則，本礦井設計中設計，一個工作面達產(chǎn)，達產(chǎn)時帶區(qū)個數(shù)為一個。開采順序一次為 2 36。采用集中布置， 2 36層集中開采。大巷運輸采用 10t 架線式電機車牽引 3t 底卸式礦車運輸，一水平采用的采煤方法為傾斜長壁采煤法，二水平采用的采煤方法為走向長壁采煤法，采用的采煤工藝為綜合機械化采煤工藝。頂板處理方法為全部跨落法。 關(guān)鍵詞： 傾斜長壁采煤法 。 走向長壁采煤法 。 全部跨落法 全套圖紙，加 153893706 II Abstract The Mine Design is a shaft design JiXi HaDa Mine Mt /a, The mine has three minable Coal Seam, consisting 23,30,36 seam and its average thickness is 6m. Industrial brands are one third, designed field of minable capacity is Mt ,it can adapt for . Average alignment in farmland in shaft lengthway average slant lengthways average rake angle in coal seam 12176。, belong to the slant the coal seam. The mine design is applied indined shalt development method, and is divided into two levels, eight mining adopts and two mining spirit of giving priority to efficiencyoriented principle, the synthesis mechanization ming coal ang one worked faces.
