1、學校代碼:學號:20112290301310128本科畢業(yè)設(shè)計說明書目:同煤集團四老溝二礦姓學系專班2.4Mt/a新井設(shè)計名:院:別:業(yè):級:指導(dǎo)教師:二O—五年六月摘要木次設(shè)計是大同礦區(qū)四老溝礦11#,14#煤層。該礦位于大同煤出東北端,距大同市25Km,距口泉站5.3Km。井田內(nèi)有公路貫穿,交通方便。據(jù)井田地質(zhì)資料:該井田煤層平均厚度9m,經(jīng)鑒定為低瓦斯礦井,瓦斯相對涌出量平均為瓦斯相對涌出量0.5774—1.3601m3/ton?/t。煤塵有爆炸危險性。煤的自燃傾向等級為易自燃。根據(jù)礦井涌水量預(yù)測,該礦井正常涌水量為122.5
2、m3/ho設(shè)計采用主斜副立單水平開拓方式,共開掘有兩個進風井(主斜井、副斜井)和一個回風井。井出共劃分有七個帶區(qū),開采煤層為11#。礦井采煤方法為綜合機械化開采方式,綜合機械化掘進,生產(chǎn)區(qū)隊設(shè)置有:一個綜采隊和兩個機掘隊。礦井達產(chǎn)吋的首采工作面位于一帶區(qū)101首采工作面,該帶區(qū)劃分為4個條帶,工作面長度為240m,推進長度為1260m,回采順序采用后退式、回采工藝中厚煤層單一走向長壁綜合機械化采煤法,采用“三八"制作業(yè)制度。采空區(qū)采用全部跨落法管理頂板。關(guān)鍵詞:礦井開拓、采煤方法、綜合機械化采煤、運輸提升、安全牛產(chǎn)。Abstract
