【正文】 綜合評(píng)定成績(jī)： 學(xué)院領(lǐng)導(dǎo)小組負(fù)責(zé)人： 年 月 日 摘 要 本設(shè)計(jì)包括三部分：一般部分、專題部分和翻譯部分。礦井開采煤層為 11煤層。 井田布置三條大巷，輔助運(yùn)輸大巷主要進(jìn)風(fēng)，其余風(fēng)經(jīng)運(yùn)輸大巷進(jìn)入井下；回風(fēng)大巷回風(fēng)。 礦井年工作日為 330 d ，每天凈提升時(shí)間為 16 h 。 專題部分： 四臺(tái)礦瓦斯綜合治理技術(shù)研究。 關(guān)鍵詞： 井田開拓；礦井通風(fēng)；煤礦安全 ； 瓦斯治理 ； ABSTRACT The design includes three parts: the general part of the thematic segment and translation section. General parts: Sitai Mine million t / a new mine ventilated safety design. Mine 5 km long northsouth, eastwest width of 6 km, an area of square kilometers, the design service life of the mine as 65a. The design uses a pair of inclined to develop a single level, stripetype arrangement. Mine is 11 coal seam mining. Band is tendency longwall retreat mining. Mechanized mining methods for integrated fullheight full once mining caving mining method. Main shaft bear the entire mine the coal, and into the wind at the same time as a security exit。 reliable and secure antiair systems, escape routes clear ability to cope with disasters mine strong. Thematic sections: Sitai Mine Gas Control Technology. For Sitai stoping process gas emission analysis and research and to take a series of measures to reduce gas emission reduction roadway gas concentration. Strive to achieve intrinsically safe mine, the mine to achieve safety escort. Translation part: Mine gas drainage and outburst control in Australianunderground coal mines. Keywords: mine field exploit。 中國(guó)礦業(yè)大學(xué) 2020 屆本科生畢業(yè)設(shè)計(jì) 第 1 頁 目 錄 一般部分 第一章 礦區(qū)概述及井田地質(zhì)特征 ...................................................................................................... 2 .............................................................................................................................. 2 礦區(qū)的地理位置 ........................................................................................................ 2 礦區(qū)氣候條件 ........................................................................................................... 3 礦區(qū)水文情況 ........................................................................................................... 4 ....................................................................................................................... 4 ............................................................................................................ 4 ............................................................................................................ 5 井田水文地質(zhì)特征 .................................................................................................... 5 ..................................................................................................... 7 煤層特征 ............................................................................................................................. 7 煤層埋藏條件 ........................................................................................................... 7 ............................................................................................................ 8 ................................................................................................................... 8 第二章 井田開拓 ............................................................................................................................. 11 井田境界及可采儲(chǔ)量 ......................................................................................................... 11 井田境界 ................................................................................................................ 11 ................................................................................................................. 11 .................................................................................. 14 ............................................................................................................................ 17 ................................................................................................ 17 .......................................................................................................... 21 ................................................................................................ 28 ................................................................................................................. 29 第三章 采煤方法及采區(qū)巷道布置 .................................................................................................... 32 煤層地質(zhì)特征 .................................................................................................................... 32 .......................................................................................................... 32 煤的特征 ................................................................................................................ 32 煤層頂?shù)装褰M成 ...................................................................................................... 32 ............................................................................................ 32 煤層的主要地質(zhì)構(gòu)造 ............................................................................................... 32 ................................................................................................ 32 ......................................................................................... 32 .................................................................................. 33 ................................................................................................ 33 .......................................................................................................... 35 ......................................................................................... 35 .......................................................................................................... 36 采煤方法 .......................................
