    资源描述:
    摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为张双楼矿 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。张双楼煤矿位于徐州市西北,距徐州市约 79km,在江苏沛县安国镇境内。 井田水平标高为-200m~-1200m,走向长 8.47~10.79km,平均 10.18km,倾斜宽平均为 2.9km,水平面积约 29.52km2。井田内可采煤层为 9 煤,煤层赋存稳定,厚度平均 4.5m,煤层倾角16~24°,平均 22°。井田内工业储量为 192.36Mt,可采储量为 124.13Mt。矿井平均涌水量为 300m3/h,相对瓦斯涌出量为 0.77m3/t,属低瓦斯矿井;煤尘有一定爆炸危险性,自燃发火期为 3~6 个月。张双楼矿年设计生产能力为 1.8Mt/a,服务年限为 53.0 年。矿井采用立井两水平开拓暗立井直接延深开拓方式;采用中央并列与两翼对角式混合通风方式;一水平标高-575m,二水平标高-950m。矿井采用走向长壁综采一次采全厚采煤法;煤炭运输采用胶带与底卸式矿车,辅助运输采用蓄电池电机车牵引矿车。矿井年工作日为 330d,每天净提升时间为 16 h,工作制度采用“三八”制。专题部分题目是:浅析矿井水的资源化。翻译部分是一篇关于复合载荷下沙层地基运转模型的论文,英文原文题目为:A plasticity model for the behaviour of footings on sand under combined loading。 关键词:立井;采区;综采;中央并列式;两翼对角式ABSTRACTThis design includes of three parts: the general part, special subject part and translated part.The general part is a new preliminary design of Zhangshuanglou Mine 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.Zhangshuanglou Mine located in the County town of Anguo which is in the northwest of Xuzhou City, and it is about 79km away from Xuzhou. The level elevation of the minefield is from -200m ~ -1200m, the coalfield length on the strike is 8.47km to 10.79km, average 10.18km, the width on the dip is 2.9km on average, the total plane area of the mine is about 29.52km2. There is only one exploring layer_number nine. The coal seam is stable, the coal seam thickness is 4.5m. Its dip angle is 16 to 24 degree, 22 degree on average. The industry reserves of the mine field are 192.36 million tons and the workable reserves are 124.13 million tons. The average inflow rate in Zhangshuanglou mine is 300 m3/h. The relative gas emission is 0.77m3/t, it is a lower gassy mine. The coal dust have a little explosion hazard and self-combustion tendency is 3 to 6 months.The productive capacity of Zhangshuanglou Mine is 1.8 million tons per year,and the service life is 53.0 years. Mine uses shaft and two-level development. The type of mine ventilation system is central abreast and wings diagonal. The first level is at -575 m, The second level is at -950 m. High cutting mining method is uses by the mine. Main roadway makes use of belt conveyor and bottom-dump wagon to transport coal resource, and mine car to be assistant transport. Mine is working days for 330 days, the net every day to enhance the time 16 hours. Mine system is “3-8“ structure.The title of special subject is “Analysis of mine water resource utilization”. The translation part is a treatise about a plasticity model for the behaviour of footings on sand under combined loading.Keywords: shaft; panels; fully mechanized mining; central parallel; wings
