1、摘要本設(shè)計礦井為雞西礦業(yè)集團盛和煤礦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,一個工作面達產(chǎn)。采用集中布置,走向長壁后退式采煤法采煤,綜合機械化回采工藝。工作面采用刮板輸送機運輸;區(qū)段運輸平巷采用帶式輸送機運輸;大巷采用14t架線式電機車牽引,3t底卸式礦車運輸
2、,采用1.5t固定式礦車作為輔助運輸。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AbstractThisdesignminepitisabundantandthecoalmine1.5Mt/anewwelldesignfortheJiximiningindustrygroup.Inthism
