本科论文设计-花园煤矿1.5Mt-a新井设计.doc

摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为花园煤矿1.5Mt/a新井设计。花园煤矿位于山东省济宁市管辖的金乡县境内，交通便利。井田走向（东西）长约3.9km，倾向（南北）长约3.0km，总面积为13.97km2。主采煤层为15＃煤，煤层倾角为2~17，平均总厚度为7.5m。井田地质条件较为简单。井田工业储量为14775万t，可采储量为12496.7万t。矿井设计生产能力为1.5Mt/a。矿井服务年限为59.50a，涌水量不大，矿井正常涌水量为86m3/h，最大涌水量为99m3/h。矿井瓦斯相对涌出量为1.732 m3/t，绝对涌出量为6.866m3/min，为低瓦斯矿井。井田开拓方式为立井单水平带区开拓。采用胶带输送机运煤，采用矿车进行辅助运输。矿井通风方式为中央并列式通风。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。专题部分题目是煤巷锚杆支护技术的研究及应用，主要是研究了对于煤巷的锚杆支护技术，对现代锚杆支护技术在煤巷方面的应用做了全面的陈述。翻译部分主要内容是关于水力压裂消突数值模拟及可控压裂技术研究，英文题目为： Numeric Analysis of Hydraulic Fracturing Technique in Preventing Outburst and the Control Technique。关键词：立井；单水平；带区；中央并列式通风ABSTRACTThis design includes three parts: the general part, the special subject part and the translation part. The general part is a new design for Huayuan mine. Huayuan mine is located in Jinxiang which comes within the jurisdiction of Ji’ning 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 3.9km,the width is about 3km，and the total area is 13.97km2.The fifteenth are the main coal seams, and its dip angle is 2~12 degree. The thickness of the mine is about 7.5m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 147.75 million tons,and the minable reserves are 124.97 million tons. The designed productive capacity is 1.5 million tons percent year, and the service life of the mine is 59.50 years. The normal flow of the mine is 86m3 per hour and the max flow of the mine is 99 m3 per hour. The relative mine gas gush is 1.732 m3/t and the absolute gush is 6.866 m3/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 ventilation mode of this mine is center juxtapos
