城郊礦240萬噸新井設(shè)計【含CAD圖紙+文檔】,含CAD圖紙+文檔,城郊,萬噸新井,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。 一般部分為城郊礦240萬噸新井設(shè)計。主采煤層為二2號煤、三2號煤，平均傾角為3°，煤層平均總厚為8.91m。井田地質(zhì)條件較為簡單。 井田工業(yè)儲量為166.6Mt，礦井可采儲量111.19Mt。礦井服務(wù)年限為64.86a，涌水量不大，礦井正常涌水量為200m3/h，最大涌水量為360m3/h。井田中各煤層瓦斯含量一般小于0.5cm3/g，屬低瓦斯礦井。各煤層均無煤塵爆炸危險。各煤層均屬不自燃發(fā)火煤層。 井田為立井單水平開拓。大巷采用膠帶運輸機運煤，輔助運輸采用礦車運輸。礦井通風(fēng)方式為混合式通風(fēng)，前期中央風(fēng)井回風(fēng)，后期帶區(qū)風(fēng)井回風(fēng)。礦井年工作日為330d，工作制度為“四六”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.準備方式帶區(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。 專題部分題目是《淺談煤礦沖擊礦壓及防治措施》 翻譯部分主要內(nèi)容為關(guān)于應(yīng)力波穿越節(jié)理時的透反射系數(shù)的研究，英文題目為：Study on the transmission and reflection of stress waves across joints. 關(guān)鍵詞：城郊煤礦； 雙立井； 單水平； 采區(qū)與帶區(qū)布置； 綜采放頂煤方法； ABSTRACT This design includes of three parts: the general part, special subject part and translated part. The designed productive capacity is 2.4 million tons percent year. The two and three is the main coal seam, and its dip angle is 3 degree. The thickness of the mine is about 8.91m in all. The mine Geology quality condition is simple by Comparison. The proved reserves of the minefield are 166.6 million tons. The recoverable reserves are 111.19 million tons. And the service life of the mine is 64.86 years. The normal flow of the mine is 200m3 percent hour and the max flow of the mine is 360 m3 percent hour. The mineral well gas gushes less than 0.5cm3/g, for low gas mineral well. All the coal seam does not have the danger of explorer, or burn by itself. The mine farmland is a single level in an inclined well to expand. The mine farmland signs the single level of well to expand for the double. The mine lane adopts the tape conveyance luck coal, assistance conveyance adoption mineral car. The well ventilated way of the mineral well is well ventilated for admixture type, expecting the central breeze well to return to breeze before, expecting to take the area breeze well to return to breeze later. The working system “four-six” is used in the Chengjiao mine. It produced 330d/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. The special subject parts of topics is 《Brief talks on mine rock burst and the control measures》. Translation part of main contents is a topic with the name of Study on the transmission and reflection of stress waves across joints.
