    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。一般部分为田陈煤矿 1.5Mt/a 新井设计。田陈煤矿位于山东省滕州市管辖的滕南矿区境内,交通便利。井田走向(东西)长约 3.7km,倾向(南北)长约 7.32km,总面积为 27.15km2。主采煤层为 3# 煤,煤层倾角为 1.3~20.56 ,平均总厚度为 5m。井田地质条件较为简单。井田工业储量为 18040 万 t,可采储量为 12776 万 t。矿井设计生产能力为 1.5Mt/a。矿井服务年限为 60.8a,涌水量不大,矿井正常涌水量为 373m3/h,最大涌水量为 400m3/h。矿井瓦斯相对涌出量为 1.33 m3/t,绝对涌出量为 2.0m3/min,为低瓦斯矿井。井田开拓方式为立井单水平上下山开拓。采用胶带输送机运煤,采用矿车进行辅助运输。矿井采用两翼对角式通风方式。矿井年工作日为 330d,工作制度为“三八” 制。一般部分共包括 10 章:1、矿区概述与地质特征;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——带区巷道布置;6、采煤方法;7、井下运输;8、矿井提升;9、矿井通风与安全;10、设计矿井基本技术经济指标。专题部分题目是浅谈深部巷道变形机理及支护技术,主要是分析了深部软岩巷道的变形机理及支护技术的探究,对深部围岩支护原理做了较深刻的探究。翻译部分主要内容是关于伽马射线传感仪在煤矿残顶煤厚度测量中的应用,英文题目为:Remnant Roof Coal Thickness Measurement with Passive Gamma Ray Instruments in Coal Mines关键词:立井;单水平;带区;两翼对角式通风ABSTRACTThis design includes three parts: the general part, the special subject part and the translation part.The general part is a new design for Tianchen mine. Tianchen mine is located in Xintai which comes within the jurisdiction of Tengzhou in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 3.7km,the width is about 7.32km,and the total area is 27.15km2.The fourth and the sixth are the main coal seams, and its dip angle is 1.3~20.56 degree. The thickness of the mine is about 5.0m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 180.4million tons,and the minable reserves are 127.76 million tons. The designed productive capacity is 1.5 million tons percent year, and the service life of the mine is 60.8 years. The normal flow of the mine is 373m3 per hour and the max flow of the mine is 400 m3 per hour. The relative mine gas gush is 1.33 m3/t and the absolute gush is 2.0m3/min, so it is a low gas mine. The mine is a single level in two shafts to develop. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilated way of opposite angle of two wing was used.The “three-eight” working system is used in the Tianchen mine. It produces for 330 days a year. 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. Underground transportation of the mine; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms of the designed mine.The topic of special subject parts is the Analysis of Gob-side Entry Retaining Technology in Mechanized Mining Face. It makes a fully comprehensive statement of gob-side entry retaining technology in mechanized mining face.Translation part is aboat Passive Gamma Ray Instruments was used in Coal Mines.The English title is “Remnant Roof Coal Thickness Measurement with Passive Gamma Ray Instruments in Coal Mines”.Keywords: Shaft; Single level; Panel; Two Wing Opposite Angle Type Well Ventilation.第 I 页目 录一般部分1
