2、硬,工業(yè)儲(chǔ)量8196.94萬(wàn)t,井田可采儲(chǔ)量6145.152萬(wàn)噸,礦井服務(wù)年限36.58年。結(jié)合礦井設(shè)計(jì)的需要和工作面產(chǎn)量及設(shè)備能力,工作面長(zhǎng)度設(shè)為200m。工作面正常涌水量30m3/h,最大涌水量100m3/h。各煤層瓦斯含量一般小于10m3/t,但8號(hào)煤層絕對(duì)瓦斯涌出量大于5m3/min,設(shè)計(jì)按高瓦斯礦井考慮。本礦主要采用傾斜長(zhǎng)壁開(kāi)采法,在局部地區(qū)用走向長(zhǎng)壁法開(kāi)采。煤炭運(yùn)輸方式選用DX型系列鋼繩芯帶式輸送機(jī),輔助運(yùn)輸方式選擇無(wú)軌膠輪車,初期開(kāi)采工業(yè)廣場(chǎng)保護(hù)煤柱周圍帶區(qū)時(shí)采用中央并列式通風(fēng),使用主斜副立井單水平帶區(qū)開(kāi)拓,首采一帶區(qū)共分為9個(gè)分帶,由于邊界不規(guī)整,推進(jìn)長(zhǎng)度19
3、50m,準(zhǔn)備方式為帶區(qū)巷道布置。本礦井設(shè)計(jì)生產(chǎn)能力按年工作330d計(jì)算,每天凈提升時(shí)間宜為18小時(shí)。礦井工作制度為“四六制”作業(yè)。關(guān)鍵詞:傾斜長(zhǎng)壁開(kāi)采;中央并列式通風(fēng);高瓦斯;帶區(qū);ABSTRACTThegraduationprojectwehavedone?is?thewhole?design?ofDatongCoalMineGroup?Yungang?1.2Mt/a,designcontentisdividedinto10chapters,theYungangMineinShanxiprovinceislocatedinthe?westernsuburbsofDatong
