该矿井可采煤层有M7、M8两层，为近水平煤层，平均倾角11，回采工艺设计煤层为M8此次设计以渝阳实际开发利用方案为基础，根据井田地质条件及煤层赋存条件，对该井田进行了初步设计本次设计中，提出了四种开拓方案，结合矿井实际情况并经过技术经济分析比较，最终选定矿井的开拓方式为斜井、平硐综合开拓井田划分为三个开采水平，即+350m水平、+150m水平和-100m水平350m水平按上、下山开采方式布置采面，开采+350m水平以上的煤层，共划分为南一区、南二区、北一区、北二区四个带区；+150m水平按上山开采方式布置采面，开采+150m～+350m的煤层，共划分为北区、东二区、东区三个带区；-100m水平，开采+150m水平以下的煤层，共划分为北三区、东三区、东四区、北四区、东五区五个带区煤层开采时采用倾斜长壁采煤方法，综合机械化采煤工艺全矿井按“一薄一中厚”配采，达产时同时开采的带区数目为2～3个，保护层开采超前突出煤层一个带区开采采煤工作面采用三八制正规作业，作业方式为“两班采煤，一班准备”同时，本次还对通风、排水、运输、供电等系统做了设计，并对各系统所用设备进行了选型；在煤与瓦斯突出、瓦斯爆炸、煤尘爆炸、顶板事故等灾害方面也提出了相应的防治措施。

There are two coal seams in this mine. They are all horizontal seams, and the average angle of them is 8. According to the geologicl conditions and occurrence conditions of coal seams, the preliminary design for the mine field isdone based on the actual development and utilized scheme for the first coal mine of Yuyang. In this design, I put up four plans, and at last I selected the combined development method with inclined shaft-shaft according to the analysis. The coal mine is devided into three working levels, +350m +50m and -100m. Working faces are arranged with upward and downward mining method in the +350m working level, which is devided into South No.1 Panel, South No.2 Panel and North No.1 Panel, North No.2 Panel , to exploit the coal seams above +350m. While in the +150m working level, which is devided into North Panel, East No.1 Panel and East No.2 Panel, working faces are arranged with upward mining method to exploit the coal seams between +150m and +350m .While in the -100m working level, which is devided into East No.3 Panel, East No.4 Panel North Panel, North No.4Panel ,and North No.5 Panel, working faces are arranged with downward mining method to exploit the coal seams down +150m . Mining to the rise in the inclined longwall mining with fully technique is used in the design. The coal seams are mined coordinately with “one thin and one medium thicks”. There are 2~3panels mined at the same time when the mine achieves its design production capacity. The cyclic operation way of coal mining workface is “two mining shifts and one preparing shift”. At the same time, I made some design for ventilation, drainage, transportation and so on. Morever, this design also presents some prevention measures on coal and gas outburst, gas explosion, coal dust explosion, mine flood, mine fire, roof accidents etc.Key words：preliminary design, horizontal seam, combined develop inclined shaft method with adit , fully mechanized mining technique, 600kt/ 目 录摘 要 IABSTRACT II前 言 11 井田概况及地质特征 31.1 井田概况 31.1.1矿区和矿井的位置、交通概况 31.1.2矿井地形、地势 41.1.3气候、温度、湿度、雨量、雨季、旱季、风向、风速 41.1.4主要河流、湖泊、水库、池塘等的分布 41.1.5本地区的地震史、结冻期、冻土期 51.1.6矿区开发史及近况 51.1.7矿区附近农业、工业、矿业概况及原材料的供应情况 61.1.8生活用水及工业用水来源；电源供给 71.2地质特征 71.2.1矿井范围内地层情况 71.2.2井田范围内外的地质构造 91.2.4顶地板岩石性质、厚度、特征 111.2.5矿井水文地质条件 121.2.6瓦斯、煤尘和煤的自燃 141.2.7煤质、牌号、用途和主要用户 151.3 勘探程度可靠性 161.3.1井田勘探的总体情况 161.3.2地质勘探程度及存在问题 162 矿井生产规模 172.1 井田境界 172.1.1井田四周边界名称描述 172.1.2井田境界确定的依据 172.1.3井田参数 172.1.4井田今后扩展、井田储量的预估 172.2井田储量 172.2.1地质储量的计算 172.2.2工业储量的计算 202.2.3保安煤柱留设种类、煤柱计算和总煤柱损失计算 212.2.4可采储量的计算 212.3矿井生产能力和服务年限 222.3.1矿井设计生产能力 222.3.2矿井设计配产后的年产量、月产量、日产量 222.3.3矿井设计服务年限 222.4 矿井工作制度 232.4.1矿井年工作天数、每天工作班数、每天工作小时数、矿井每天净运输、提升小时数 232.4.2矿井采煤工作面工作方式 233 井田开拓 243.1 概述 243.1.1矿区内相邻生产矿井开拓方式概述和评价 243.1.2矿井开拓方式选择的影响因素 263.2 开拓方案的提出和选择 273.2.1 广泛提出开拓方案 273.2.2 开拓方案的分析、选择、比较 323.2.3 选定最佳开拓方案 343.3 选定开拓方案的开拓系统详述 343.3.1井筒形式和数目 343.3.2井筒位置、坐标、主要尺寸 353.3.3开采水平划分 363.3.4主要石门特征 363.3.5井底车场形式选择 363.3.6运输大巷和总回风巷特征 373.3.7煤层群的分组及联系方式 403.3.8带区划分 403.4井筒布置和施工 403.4.1井筒布置及井筒装备 403.4.2井筒延伸初步设想 443.5 井底车场及硐室 443.5.1井底车场形式的确定 443.5.2井底车场的布置 443.5.3井底车场机电硐室及其它硐室 443.5.4井底车场主要巷道及各个硐室的支护方式 443.6开采顺序 453.6.1水平开采顺序 453.6.2带区开采顺序 453.6.3煤层开采顺序 454 采煤方法和带区巷道布置 464.1 采煤方法的选择 464.1.1 邻近矿井采煤方法现状和评价 464.1.2 采煤方法选择 474.2 带区概述 474.2.1 设计带区的位置、边界、范围 494.2.2 设计带区储量、生产能力和服务年限 494.3 带区巷道布置 524.3.1 分带划分 524.3.2 带区巷道布置 524.3.3 分带斜巷布置 534.3.4带区车场 534.3.5 带区煤仓 534.3.6 带区联络巷道 534.3.7 带区硐室 544.4 带区生产系统 544.4.1 煤炭运输系统。
