步成為本地區(qū)的主導產業(yè)和重要經濟來源之一。礦井井下所選用的電氣設備均具有防爆性能。 礦井為 雙回路供電。冰凍期較長,最長凍土天數為 167 天( 1976 年),最大凍土深度為 米( 1964 年 3 月 1 日)。 氣象及地震 本區(qū)屬于半沙漠、半干旱溫帶大陸性氣候,其特征是太陽幅射強烈、日照豐富、干旱少雨、風大沙多,無霜期短,冬季漫長而寒冷,夏季炎熱而短暫。海拔標高為 ~ 米之間,最大地形高差 。礦井距包神鐵路石圪臺集裝站 40km,距唐公塔集裝站 148km,距包頭 189km,至鄂爾多斯市 89km,交通運輸條件比較方便。 9. The ventilation and the safety operation of the mine。 layout of panels。 翻譯部分 是一篇 關鍵詞: 斜硐 ; 盤 區(qū); 大采高 ;無軌運輸; 混合式通風 ABSTRACT Keywords: This design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Lijialiang mine. Lijialiang mine lines in south of eerduosi in NeiMenggu province. The traffic of road and railway is very convenience to the mine. The run of the minefield is ,the width is about km, well farmland total area is ㎞ six is the main coal seam, and its dip angle is 1 degree. The thickness of the mine is about in all. The proved reserves of the minefield are million tons. The recoverable reserves are million tons. The designed productive capacity is 4 million tons percent year, and the service life of the mine is years. The normal flow of the mine is 30 m3 percent hour and the max flow of the mine is 60 m3 percent hour. It is bituminous coal with low mine gas emission rate and coal spontaneous bustion tendency, and it’s a coal seam liable to dust explosion. The well farmland is a single level in an inclined well to expand. The working system ―threeeight‖ is used in the Lijialiang mine. It produced 330d/a. This design includes ten chapters: outline of the mine field geology。 礦井年工作日為 330 d, 每天凈提升時間 16 h。 平均埋深為 120m; 礦井正常涌水量為 30m3/h,最大涌水量為 60 m3/h;煤層硬度系數 f=,煤質 為 低中灰、低硫、特低磷~低磷、高熱值 不粘煤 ;礦井絕對瓦斯涌出量為 m3/min,屬低瓦斯礦井;煤層有自燃發(fā)火傾向,發(fā)火期 40~60 天 ,煤層具有強爆炸危險 性 。主采煤層 一層,即 6 號煤 層 ,傾角 1~3176。 一般部分為 伊泰集團李家梁 煤礦 400 萬 t 新井設計 , 共 分 10 章 : 及井田地質特征 ; ; 、 設計生產能力 及 服務年限 ; ; 盤區(qū) 巷道布置 ; ; ; ; ; 基本 技術經濟指標。 伊泰集團李家梁煤礦 位于 內蒙古自治區(qū)東勝煤田勃牛川礦區(qū)西南部 , 距曹~羊公路 ,經曹~羊公路 37km 與 109 國道相連。 ,平均厚度 。 礦井采用斜井 平硐 單 水平 聯(lián)合開拓方式 , 前期采用中央并列式通風,后期采用兩翼對角式通風。礦井 工作制度 為: 實行 “ 三八 ”制 作業(yè), ( 兩 班生產,一班檢修),每日 兩 班出煤。 and the reserves of mine。 6. The method used in coal mining。 basic economic and technical norms. The monographic study is Study and Application of Packaged Equipments of great mining height and fullseam mining in thick coal seam,and it gives a thermal analysis of the underground pressure modeled by . Translation part of main contentses is an analysis model concerning rock bolts, English topic is:Analytical models for rock bolts. 一般部分 ............................................................................................................................. 5 1 礦井概況與地質特征 ...................................................................................................... 5 礦井概況 ............................................................................................................... 5 井田地質特征 ......................................................................................................... 6 煤層特征 ............................................................................................................ 10 2 井田境界和儲量 ............................................................................................................. 15 井田境界 ............................................................................................................... 15 礦井工業(yè)儲量 ........................................................................................................ 16 礦井可采儲量 ........................................................................................................ 16 3 礦井工作制度、設計生產能力及服務年限 ....................................................................... 19 礦井工作制度 ........................................................................................................ 19 礦井設計生產能力及服務年限 ............................................................................... 19 4 井田開拓 ........................................................................................................................ 22 井田開拓的基本問題 ............................................................................................. 22 ....................................................................................................... 30 5 準備方式 ——盤區(qū)巷道布置 ............................................................................................ 33 ........................................................................................................ 33 ..................................................................................... 34 ............................................................................................ 39 6 采煤方法 ........................................................................................................................ 41 ....................................................................................................... 41 ....................................................................................................... 50 7 井下運輸 ........................................................................................................................ 52 述 ..................................................................................................................... 52 ..................................................................................... 53 ..................................................................................... 55 8 礦井提升 ........................................................................................................................ 59 .................................................................................. 59 ....................................................................................................... 59 9 礦井通風及安全 ............................................................................
