Design the tons of coal mine cost 110 yuan/t. The projects section discusses the topic is sihe coal mine gas treatment and utilization technology. Using ground extraction and prehensive utilization Special subject part mainly introduces the treatment and multipurpose use of mine water. Translation part is about international evaluation of injury rates in coal mining. The topic is ―International Evaluation Of Injury Rates In Coal Mining‖ Keywords: vertical shaft。 Plan 4: two level mining, cutting extends to the vertical Wells 800 m level. Through the technical and economic parison, ultimately determine the optimal scheme for option 3. Will the Lord CaiMeiCeng divided into two levels, a level elevation 550 m, two level elevation 800 m, for large fault will be partmentalized into partmentalized is divided into two parts, partmentalized south south service scope for a level for two level, northern service scope. Design the first panel adopts mining ways to prepare, face, the time length m in coal mining method, all the high across fell method processing goaf. Mine using 38 exercise, two class production, bus overhaul. Every four cycle shift, rijin eight circulation, circulation m, daily output footage by belt conveyor by t, auxiliary coveyance fixed box harvesters. Equipped with a set of main shaft 12 t double skip and a set of 12 t single skip belt balance hammer carry coal, a 3 t harvesters pregrouting equipment with double bikes for balance hammer cage auxiliary coveyance task. Mine using twowing diagonal type ventilation. Mine ventilation easy period should always be airflow 10271032 m3 / min, mine ventilation total resistance 1588 Pa, wind resistance N Scheme ii: single level down the shaft mining, in 550 level, rock DaHang。 For mine absolute gas flowvolume m3 / min, belong to low gas mine。 Mine normal section for 383 m3 / h, maximum section for 520 m3 / h。 翻譯部分是一篇關(guān)于工作面煤塵控制的研究的論文，英文原文題目為： International evaluation of injury rates in coal mining 關(guān)鍵詞： 立井；上山開采；大采高；雙巷掘進；兩翼對角式 ABSTRACT This design includes three parts: general design part, project design part and translation parts. General part is Sun Tuan Mt/a mine of new Wells design. Sun Tuan mine located in anhui province huaibei city. The coal mine, the south territory renlou coal mine with borders, north and northeast willow from SuZhouShi partmentalized adjoins, about 23km. There can be many highway partmentalized SuZhouShi and MengChengXian huaibei city, to. East, west and the field respectively jinghu railway, south Sui railway and mining area was Tuan) ~ railway green (model (ridge) feeder after. The traffic is very convenient. Whole field northsouth km long, 3 ~ 5km tilt width something km2, with a total area of about it. The Lord CaiMeiCeng layer, namely 10 176。設(shè)計礦井的噸煤成本 110 元 /t。礦井通風(fēng)困難時期礦井總風(fēng)量 4150 m3/min，礦井通風(fēng)總阻力 2200Pa，風(fēng)阻 N通風(fēng)容易時期礦井總需風(fēng)量 4150 m3/min，礦井通風(fēng)總阻力 1588 Pa，風(fēng)阻 N主井裝備一套 12 t 雙箕斗和一套 12 t 單箕斗帶平衡錘提煤，副井裝備一對 3 t 礦車雙層單車罐籠帶平衡錘擔(dān)負(fù)輔助運輸任務(wù)。 生產(chǎn)班每班 3 個循環(huán)，日進 7 個循環(huán)，循環(huán)進尺 m，日產(chǎn)量 5495 t。 設(shè)計首采區(qū)采用采區(qū)準(zhǔn)備方式，工作面長度 250 m，采用一次采全高采煤法，全部跨落法處理采空區(qū)。通過技術(shù)經(jīng)濟比較，最終確定方案三為最優(yōu)方案。 根據(jù)井田地質(zhì)條件，提出四個技術(shù)上可行開拓方案。井田地質(zhì)條件簡單。厚約 3 m。 全井田南北走向長 ，東西傾斜寬 3～ 5km，面積約 。井田外東側(cè)、西北側(cè)和南側(cè)分別有京滬鐵路、濉阜鐵路和礦區(qū)鐵路青（疃）～蘆（嶺）支線經(jīng)過。孫疃煤礦位于安徽省淮北市濉溪縣境內(nèi)，其南與任樓礦井接壤，北與楊柳井田毗鄰，東北距宿州市約 23km。 摘 要 本設(shè)計包括三個部分：一般設(shè)計部分、專題設(shè)計部分和翻譯部分。 一般部分為孫疃礦 Mt/a 的新井設(shè)計。井田內(nèi)有多條公路可至淮北市、宿州市和蒙城縣。交通十分方便。主采煤層一層，即10 號煤層，平均傾角 17176。井田工業(yè)儲量為 ，可采儲量 Mt，礦井服務(wù)年限為 a。表土層平均厚度 50 m；礦井正常涌水量為 120 m3/h，最大涌水量為 220m3/h；煤層硬度系數(shù) f=；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 3~6 個月，煤塵具有爆炸危險性。方案一：立井單水平上下山開采，水平在 550m, 煤層大巷；方案二：立井單水平上下山開采， 在 550 水平，巖層大巷；方案三：立井兩水平暗斜井開采 延伸至 800 m 水平；方案四：立井兩水平開采，立井井延伸至 800 m水平。將主采煤層劃分為兩個水平，一水平標(biāo)高 550 m，二水平標(biāo)高 800 m，因井田走向大斷層將井田分為南北兩部分，井田南部為一水平服務(wù)范圍，井田北部為二水平服務(wù)范圍。礦井采用 ―三八 ‖制作業(yè)，兩班生產(chǎn)，一班 生產(chǎn)并 檢修。 大巷采用帶 式輸送機運煤，輔助運輸采用 t 固定箱式 礦車。礦井采用兩翼對角式通風(fēng)。s2/m8，等積孔 m2，礦井通風(fēng)容易。s2/m8，等積孔 ，礦井通風(fēng)中等困難。 專題部分題目是淺談煤礦礦井水處理及利用。 obliquity 17, average coal seam, thick about 3 m.
