1、摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为姚桥煤矿1.2Mt/a新井设计。姚桥煤矿座落在江苏省沛县和山东省微山县境内,交通便利。井田走向(东西)长约5km,倾向(南北)长约4km,总面积为18.8km2。主采煤层为7、8 、16、21煤,煤层倾角为516,平均总厚度为4.86m。井田地质条件较为简单。井田工业储量为12844万t,可采储量为9128万t。矿井设计生产能力为1.2Mt/a。矿井服务年限为58.51a,涌水量不大,矿井正常涌水量为250m3/h,最大涌水量为400m3/h。矿井瓦斯相对涌出量为0.0054m3/t,绝对涌出量为0.0384m3/min,为低瓦
2、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。专题部分题目是沿空掘巷小煤柱稳定机理分析。翻译部分主要内容是关于煤炭火灾的研究,英文题目为:Coal fires关键词:立井;单水平;带区;中央并列式通风ABSTRACTThis design
3、includes three parts: the general part, the special subject part and the translation part.The general part is a new design for Yaoqiao mine. Yaoqiao mine is located in jiangsu and shandong province WeiShanXian peixian county territory. It is very convenient to get to the mine in terms of both highwa
4、y and railway. The length of the coalfield is 5km,the width is about 4km,and the total area is 18.8km2.The 7、8 、16、21 are the main coal seams, and its dip angle is 516 degree. The thickness of the mine is about 4.86m in all. The geologic structure of this coalfield is simple.The recoverable reserves
5、 of the coalfield are 128.44 million tons,and the minable reserves are 91.28 million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 58.51 years. The normal flow of the mine is 250m3 per hour and the max flow of the mine is 400 m3 per hour
6、. The relative mine gas gush is 0.0054 m3/t and the absolute gush is 0.0384 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 venti
7、lation mode of this mine is center juxtapose form.The “three-eight” working system is used in the Zhaizhen 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 m
