1、摘要本設(shè)計礦井為雞西礦業(yè)集團(tuán)盛和煤礦1.5Mt/a新井設(shè)計。此礦區(qū)內(nèi)有四層煤全區(qū)可采，分別是23#、34-2#、48#和54#，平均總厚度8.4米。煤層工業(yè)牌號為1/3焦煤和焦煤，煤層傾角為20°，地質(zhì)構(gòu)造條件簡單。設(shè)計井田的工業(yè)儲量為169.83Mt，可采儲量為123.9Mt，礦井服務(wù)年限為59年，本礦井設(shè)計采用立井開拓方案，劃分三個水平，采用上山開采，一個工作面達(dá)產(chǎn)。采用集中布置，走向長壁后退式采煤法采煤，綜合機(jī)械化回采工藝。工作面采用刮板輸送機(jī)運(yùn)輸；區(qū)段運(yùn)輸平巷采用帶式輸送機(jī)運(yùn)輸；大巷采用14
2、t架線式電機(jī)車牽引，3t底卸式礦車運(yùn)輸，采用1.5t固定式礦車作為輔助運(yùn)輸。通風(fēng)方式為分區(qū)抽出式通風(fēng)。工作面長度為220m，年工作日為330d，提升方式采用1對16t箕斗提升，凈提升時間為16h，采用〝三八〞工作制。關(guān)鍵詞可采儲量分區(qū)抽出式走向長壁由于本設(shè)計時間有限，本人的工作能力及現(xiàn)場經(jīng)驗(yàn)也有限，因此在本設(shè)計中會出現(xiàn)一些問題，請各位專家及老師批評指正。全套圖紙，加15389370679AbstractThisdesignminepitisabundantandthecoalmine1.5Mt/an
