陳四樓礦2.4Mta新井設(shè)計【含CAD圖紙+文檔】,含CAD圖紙+文檔,陳四樓礦,mta,設(shè)計,cad,圖紙,文檔 摘 要 本設(shè)計包括三個部分：一般部分、專題部分和翻譯部分。 一般部分為陳四樓2.4 Mt/a新井設(shè)計。陳四樓煤礦位于河南省永城市西北郊區(qū)，交通較為便利。井田傾向（東西）長約6.88 km，走向（南北）長約3.05 km，井田總面積為26.13 km2。主采煤層為二2煤層，平均傾角為9.73°，煤層平均厚度為7.43 m。井田地質(zhì)條件較為簡單。 井田工業(yè)儲量為273.09 Mt，礦井可采儲量190.48 Mt 。該礦井服務(wù)年限為56.69 a，涌水量不大，礦井正常涌水量為894 m3/h，最大涌水量為1200 m3/h。礦井瓦斯涌出量較低，為低瓦斯礦井。 井田為立井單水平上下山開拓；長壁放頂煤采煤法；礦井通風(fēng)方式為中央并列式。 礦井年工作日為330d，工作制度為“三八”制。 一般部分共包括10章：1.礦區(qū)概述及井田地質(zhì)特征；2.井田境界和儲量；3.礦井工作制度及設(shè)計生產(chǎn)能力、服務(wù)年限；4.井田開拓；5.準備方式-盤區(qū)巷道布置；6.采煤方法；7.井下運輸；8.礦井提升；9.礦井通風(fēng)與安全技術(shù)；10.礦井基本技術(shù)經(jīng)濟指標。 專題部分的題目深部礦井巷道支護技術(shù)。主要分析了深部礦井巷道支護問題，提出了一些先進的巷道支護技術(shù)并予以討論。 翻譯部分主要內(nèi)容煤礦瓦斯抽放與瓦斯突出控制在澳大利亞礦井下的應(yīng)用，英文題目為：Mine gas drainage and outburst control in Australian underground coal mines ABSTRACT This design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Chensilou mine. Chensilou mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 6.88 km ,the width is about 3.05 km，well farmland total area is 26.13km2.The two is the main coal seam, and its average dip angle is 9.73 degree. The thickness of the mine is about 7.43 m in all. The proved reserves of the minefield are 273.09 Mt. The recoverable reserves are 190.48 Mt. The designed productive capacity is 2.4 Mt percent year, and the service life of the mine is 56.69 years. The normal flow of he mine is 894 m3 percent hour and the max flow of the mine is 1200 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well. The well farmland is one levels in vertical shaft development; the coal mine is the longwall mining;the centralized ventilation. The working system “three-eight” is used in the Chensilou mine. It produced 330 d/a. This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms. Special subject parts of topics is Technology of supporting mine roadway in deep. Main problems analysis in deep mine roadway, made a number of roadway support in advanced technologies and will be discussed. Translation part of main contentses is Mechanism andcontrol of ground residual deformation over longwall goaf.English topic is: Mine gas drainage and outburst control in Australian underground coal mines
