1、摘要本設(shè)計礦井為雞西礦業(yè)集團(tuán)東山礦1.2Mt/a新礦井設(shè)計。地質(zhì)構(gòu)造為單斜構(gòu)造，共有可采煤層為4層，分別為3#上、3#下、6#A和6#B煤層總厚度為5.6m。設(shè)計井田的工業(yè)儲量為112.24Mt,可采儲量為95.19Mt，礦井的設(shè)計服務(wù)年限為57a。煤層傾角為10°屬緩傾斜煤層，本礦井設(shè)計采用雙立井開拓方式，劃分為三個水平，3個采區(qū)，2個工作面達(dá)產(chǎn)，采用采區(qū)式準(zhǔn)備方式，達(dá)產(chǎn)時采區(qū)個數(shù)為兩個。大巷運(yùn)輸采用14t架線式電機(jī)車牽引3t底卸式礦車運(yùn)輸，區(qū)段運(yùn)輸平巷采用帶式輸送機(jī)，輔助運(yùn)輸為1.5t固定式礦車，工作面

2、采用刮板運(yùn)輸機(jī)。采煤方法為走向長壁倒退式采煤法，采煤工藝為普通機(jī)械化采煤工藝。工作面的支護(hù)方式采用單體液壓支柱和鉸接頂梁聯(lián)合支護(hù)，頂板處理方法為全部跨落法。提升設(shè)備為主井采用箕斗提升，副井采用罐籠提升。工作面年工作日為330d，采用“三、八”工作制，工作面長為160m，循環(huán)進(jìn)度為0.6m，每日進(jìn)刀次數(shù)為5刀。通風(fēng)方式是分區(qū)抽出式。由于本人水平有限，工作能力及現(xiàn)場經(jīng)驗不足，故本設(shè)計中出現(xiàn)一些問題在所難免，請各位專家老師不吝賜教。關(guān)鍵詞：礦井設(shè)計;走向長壁采煤法;全部跨落全套圖紙，加AbstractThedes
