采礦工程畢業(yè)設(shè)計(jì)論文-雙鴨山礦業(yè)集團(tuán)集賢煤礦24mta新井設(shè)計(jì)(已修改)

　

【正文】 I 摘 要 本設(shè)計(jì)新井為 雙鴨山礦業(yè)集團(tuán)集賢 煤礦 ，共有 3層設(shè)計(jì)可采煤層，平均總厚度為 m。設(shè)計(jì)井田的可采儲(chǔ)量為 241Mt。服務(wù)年限為 73a。單水平 開(kāi)采。 本設(shè)計(jì)礦井采用雙斜 井的開(kāi)拓方式，集中大巷及采區(qū)石門(mén)的大巷布置方式。共劃分 3個(gè)采區(qū)，其中首采區(qū)為 一個(gè)采區(qū) ，投產(chǎn)工作面 1 個(gè) 。本設(shè)計(jì)采區(qū)為南 一， 大 巷道裝車(chē)式下部車(chē)場(chǎng)，采用 分區(qū) 式通風(fēng)，綜合放頂煤 采煤。年工作日為 300 天，采用“四、六”式工作制，工 作 面長(zhǎng)為 200m，每刀進(jìn)度為 ，每日割 6刀。提升設(shè)備為主 井采用大傾角帶式運(yùn)輸機(jī)提升 。 關(guān)鍵詞 : 回采工藝 放頂煤 全套圖紙，加 153893706 II Abstract The task of this design is to construct a tons new shaft for ShuangYaShan Ming mine has four minable Coal Seam, and its average thickness is meters. Designed field of minable capacity is 241 million tons. It can adapt for 73years, and is divided into one level. This mine shaft is applied to double indined shaft development method。 Layout of gathing gallergand mining district eross heading。 This level is divided into 8 mining districts and 1 worked faces. Time of constructing shaft is months. This worked fece is middle 1 and right 1 worked face, ords 300 days every year. Adapt “ foursix” work situation, work face is 200 meters length of circle is , and times is 6 one day. Key words: mining technology。 longwall coal mining method Put top coal III IV 目 錄 摘要 ...............................................................................................................................
