采礦工程畢業(yè)設(shè)計論文-雙鴨山礦業(yè)集團(tuán)東榮四礦09mta新井設(shè)計(已修改)

　

【正文】 I 摘 要 本設(shè)計 礦井 為雙鴨山礦業(yè)集團(tuán)東 榮 四礦 ，共有 3層設(shè)計可采煤層，平均總厚度為 ， 煤的工業(yè)牌號 以肥煤為主 。設(shè)計井田的可采儲量為 。服務(wù)年限為 。劃分兩個水平開采。 本設(shè)計礦井采用雙立井的開拓方式 ，分組集中大巷的 布置方式。 第一水平共劃分 14采區(qū)，其中首采區(qū)為 2 個，投產(chǎn)工作面 2個。本設(shè)計采區(qū)為東一上采區(qū)，采用中央分列式通風(fēng)，普通機(jī)械化采煤。工作面年工作日為 330 天，每日凈提升時間為 16小時，采用三八工作制，工作面長為 149m，滾筒截深 ，日進(jìn)刀數(shù) 為 7刀。 提升設(shè)備為主井采用箕斗提升，副井采用罐籠提升。 關(guān)鍵詞： 開拓 水平 采區(qū) 走向長壁采煤法 全套圖紙，加 153893706 II Abstract The task of this design is to construct a million tons per year new shaft for Shuangyashan Ming Administration,This mine has three minable Coal Seam， and its average thickness is meters， types of coal seam is fat coal. Designed field of minable capacity is million tons. It can adapt for years， and is divided into two levels. This mine shaft is applied to double indined shaft development method。 Layout of gathing gallergand mining district eross heading。 The first level is divided into 6 mining districts and 2 worked faces. This worked district is east 1 worked face. Ords 330 days every year. Adapt “ threeeight” work situation， work face is 149 meters length of circle is meters， and times is 7 one day. Key Words: Expand Level district longwall coal mining method III i 目 錄 摘 要 ........................................................................................................................
