1、摘 要本设计分为三部分:一般部分、专题部分和翻译部分。概述了河南省永城市西北部陈角矿的设计概况。公路和铁路的交通对矿山很方便。矿区宽度3.4km,宽度约6.2km,井田总面积21.30km2,二是主煤层,平均倾角6度。矿井的总厚度约为5.93米。矿区探明储量1.5万吨,设计生产能力150万吨/年,矿山使用年限53年。矿井正常流量为250立方米小时,最大流量为380立方米小时。对于低瓦斯矿井,矿井瓦斯涌出量较低。井田为竖井开发的两级,科尔矿山为长壁开采,集中通风。城郊矿采用“三八”工作制。它产生了330天/年。本次设计共分十章:1、矿区地质概况;2、矿区边界及储量;3、矿井使用年限及工作制度;4
2、、煤田开发工程;5、条带区布置;6。煤矿开采中使用的方法;7。地下运输;8.矿井提升;9.矿井通风与安全生产;10.基本经济技术规范。本节的题目是分析倾斜煤巷支护技术的原理和应用,分析了倾斜煤巷支护技术的原理,并对其前景和优缺点进行了深入探讨。翻译部分的主要内容是基于离散单元法对放顶煤过程进行数值模拟,英文倾斜度为:离散单元法对放顶煤过程进行数值模拟。关键词:竖井;条带区;综放顶煤;架空电力机车运输;集中并列通风ABSTRACTThis design includes of three parts: the general part, special subject part and tran
3、slated part.The general part is a new design of chengjiao mine.chenjiao mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 3.4 km ,the width is about 6.2 km,well farmland total area is 21.30 km2.The two i
4、s the main coal seam, and its average dip angle is 6 degree. The thickness of the mine is about 5.93 m in all. The proved reserves of the minefield are 150 Mt. The designed productive capacity is 1.5 Mt percent year, and the service life of the mine is 53 years. The normal flow of the mine is 250 m3
