摘要
本次毕业设计的内容为松藻煤电有限责任公司渝阳煤矿(60万吨/年)初步设计。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。

ABSTRACT
This graduation design is a preliminary design (600kt/a) for the first coal mine of Yuangyang in Songzao Coal-Electricity Limited Liability Company. 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.
