    中国矿业大学 2012 届本科生毕业设计摘要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为孙村 1.8Mt/a 新井初步设计,共分 10 章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度、设计生产能力及服务年限;4.井田开拓;5.准备方式—采区巷道布置;6.采煤方法;7.井下运输;8.矿井提升;9.矿井通风与安全技术;10.矿井基本技术经济指标。孙村煤矿位于山东省泰山东侧的新泰市新汶办事处孙村镇境内,地处新汶煤田东部,位居山东新汶矿业集团公司腹地,东与张庄煤矿,西与良庄煤矿相邻,南依蒙山山系,北与莲花山相望,柴汶河自东向西流经井田之上。主井井口地理坐标:东径 117°40′57″,北纬 35°52′16″,东北距新泰市 9km,西距磁窑 68km,西北距济南168km。孙村煤矿位于山东省泰山东侧的新泰市新汶办事处孙村镇境内,地处新汶煤田东部,位居山东新汶矿业集团公司腹地,东与张庄煤矿,西与良庄煤矿相邻,南依蒙山山系,北与莲花山相望,柴汶河自东向西流经井田之上。矿井范围东西以人为边界为界,南边以煤层露头为界,北边以自然边界为界。井田走向长度为 7.82km,倾斜长为 5.03-6.58km,井田水平宽度为 5.5km,水平面积为 43.62 平方公里。孙村煤矿交通方便,磁(磁窑)莱(莱芜)铁路穿过矿井生产区与生活区,与京沪铁路接轨,铁路运输可畅通全国各地。矿井驻地公路四通八达,井田南部有京沪高速公路和蒙馆公路;井田北部有直通泰安市的一级公路和博徐公路,并与京沪高速公路交汇。矿井最大涌水量为 1206m3/时,正常涌水量为 900 m3/时;煤质为气煤;煤层的埋藏深,厚度大,储量丰富。矿井属低瓦斯矿井,煤层无自然发火危险,煤尘有爆炸性。矿井采用综合多水平开拓,采用中央并列式和两翼对角式混合通风。一矿一面,采煤方法为长壁综采一次采全高开采。煤炭运输采用阻燃胶带和底卸式矿车,辅助运输采用蓄电池电机车牵引矿车。矿井年工作日为 330 d,每天净提升时间 16 h。矿井工作制度为“三八” 制。专题部分题目是煤矿冲击地压及其防治。翻译部分是一篇关于煤尘处理的论文,英文原文题目为:Coping with Coal Dust。关键词:斜井;采区;综采;中央并列式;两翼对角式中国矿业大学 2012 届本科生毕业设计AbstractThis design includes of three parts: the general part, special subject part and translated part.The general part is a new preliminary design of Pansan wells that annual output is 1.8Mt . The design includes ten chapters: 1. Mine and mine geological features outlined; 2. Waida realm and reserves; 3. Mine system, design capacity and length of service; 4. Waida develop ; 5. to prepare the way - with the district roadway layout; 6. mining methods; 7. underground transport; 8. mine hoist; 9. mine ventilation and security technologies; 10. mine the basic technical and economic indicators.Suncun Mine is located in Shandong Province Taishan 's Xintai City the east side of the territory of the Suncun village , located in the eastern part of the Xinwen coal field , the highest in the Shandong Xinwen Mining Group Company hinterland of East and Zhang Mine , West , and good coal mine adjacent Monsanto mountains, North Lianhuashan sea , according to South Cai wen he flows through the mine field from east to west above . The main wellhead geographical coordinates : east longitude 117 ° 40'57 “ , latitude 35 ° 52'16 “ , from the Northeast to Xintai City 9km west ciyao 68 km northwest from the Jinan 168km .Suncun Mine is located in Shandong Province Taishan 's Xintai City ,the east side of the territory of the Suncun village , located in the eastern part of the Xinwen coal field , the highest in the Shandong Xinwen Mining Group Company hinterland of East and Zhang Mine , West , and good coal mine adjacent Monsanto mountains, North Lianhuashan sea , according to South Cai wen he flows through the mine field from east to west above . Mine the scope of things to the artificial boundary as the boundary , south of the coal seam outcrop north, the natural boundary . Ida strike length of 7.82km , the inclined length of 5.03 - 6.58km , Ida horizontal width of 5.5km , the level of an area of 43.62 square kilometers .The Profitable coal convenient , magnetic ( ciyao , ) Levin (Laiwu) railway through the mine production area and living area , and integration with the Beijing-Shanghai Railway , rail transport can be smooth across the country . The mine Resident highways , Ida south Beijing-Shanghai Expressway and Mongolia Museum Road ; Ida northern part of a highway through the Tai'an City and Bo Xu Highway and Beijing-Shanghai Expressway intersection .Mine the maximum discharge is 1206m3/h, the normal discharge is 900 m3/h; coal to gas coal; all mine gas emission in the absolute maximum for the 50 m3/min, a low-gas mines; coal dust explosion has a certain risk.Mine uses shaft single the level of development and uses Central parallel and the two wings of the roles of ventilation.Side of a mine ,mining method for a fully mechanized longwall mining height. Coal Transportation by the end of flame-retardant tape and bottom dump car . Auxiliary transport uses battery Locomotive traction tramcar.Mine is working days for 330 days, the net every day to enhance the time 16 hours. Mine system is “38“ structure.Special subject part is about the research of Deep roadways Supporting Technology.
