【正文】 I 摘 要 本設(shè)計(jì)新井為 大雁礦務(wù)局一礦 ，共有 4 層可采煤層，平均 厚度為 。設(shè)計(jì)井田的可采儲(chǔ)量為 。服務(wù)年限為 61a。劃分 一 個(gè)水平開(kāi)采。 井田平均走向長(zhǎng) 4200m，平均傾斜長(zhǎng) 2020m，煤層平均傾角 10176。，屬于緩傾斜煤層。 本設(shè)計(jì)礦井采用雙立井的開(kāi)拓方式，集中大巷布置方式。共劃分 10 個(gè)帶區(qū)，其中首帶區(qū) 1 個(gè)，達(dá)產(chǎn)工作面 1 個(gè)。本設(shè)計(jì)帶區(qū) 采用最新采礦工藝 ，大巷裝車(chē)式下部車(chē)場(chǎng)， 綜合 機(jī)械化采煤。年工作日為 330 天， “ 四 、 六 ”式工作制，工作面長(zhǎng)為 180m，每刀進(jìn)度為，每 日割 9 刀。 提升設(shè)備為主井采用箕斗提升，副井采用罐籠提升。 由于井田 為 緩傾斜煤層， 且 煤層地質(zhì)條件 賦予穩(wěn)定 ，決定本井田內(nèi)全部采用傾斜長(zhǎng)壁采煤法開(kāi)采。 由于本人知識(shí)有限，缺乏一定的現(xiàn)場(chǎng)經(jīng)驗(yàn)。因此，本設(shè)計(jì)中難免會(huì)出現(xiàn)一些問(wèn)題，請(qǐng)各位專(zhuān)家老師不吝指正。 關(guān)鍵詞 可采儲(chǔ)量 采煤工藝 傾斜開(kāi)采 全套圖紙，加 153893706 II Abstract The task of this design is to construct a tons new shaft for Shuangyashan Ming mine has three minable Coal Seam,and its average thickness is fie ld of minable capacity is million tons. It can adapt for 58years, and is divided into tw o levels. Average alignment in farmland in w ell lengthw ays 4500 ms, average slant lengthw ays 4300ms, average rake angle in coal seam 11176。, belong to the the slant the coal seam. This mine shaft is applied to double indined shaft development method。 Layout of gathing gallergand mining district eross heading。 The well farmland turns to is divided into totally 15 adopt the zone mines and 2 w orked faces. This worked fe ce is w est six w orked face, words 300 days every year. Adapt “theeeight” work situation, work face is 135 meters length of circle is , and times is 4 one day. Because the well farmland slant length is bigger, and incline the coal seam for the , a nd coal seam geology condition etc. factor effects, deciding this well farmland inside the plete adoption slant. Because my limit working ability and time. There must be lots of faults in this design. I plead with dirextors point them out and redify it, and I will accept it sincerely and humblely. Key words Recoverable reserves The technology of coal mining Adoption slant I 目錄 摘 要 ....................................................................................................
