【正文】 I 摘 要 本設(shè)計新井為 雙鴨山礦業(yè)集團集賢 煤礦 ，共有 3層設(shè)計可采煤層，平均總厚度為 m。設(shè)計井田的可采儲量為 241Mt。服務(wù)年限為 73a。單水平 開采。 本設(shè)計礦井采用雙斜 井的開拓方式，集中大巷及采區(qū)石門的大巷布置方式。共劃分 3個采區(qū)，其中首采區(qū)為 一個采區(qū) ，投產(chǎn)工作面 1 個 。本設(shè)計采區(qū)為南 一， 大 巷道裝車式下部車場，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輸機提升 。 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 ...............................................................................................................................
