采矿工程毕业设计-陈四楼矿240万吨新井通风安全设计

XX大学20**届毕业设计（论文）题目：陈四楼矿240万吨新井通风安全设计班级：学号：姓名：指导教师：陈四楼矿240万吨新井通风安全设计摘要本设计分为一般部分和科技英语翻译部分。

一般部分为永城矿区陈四楼煤矿240万吨/年新井通风安全设计；科技英语翻译部分为计算机映射采矿中的断层。

陈四楼煤矿设计生产能力为240万吨/年，矿井服务年限为55年，采用立井单水平，回风大巷布置在岩层中作为本矿井的开拓方案。

水平设在-520米。

带区布置采用带区单一煤层分带巷道布置，初期在一带区布置一个综合机械化放顶煤工作面，采用倾斜长壁一次开采。

矿井采用抽出式通风方式，轨道斜巷进风，皮带斜巷回风。

根据通风容易和困难时期的风量和通风阻力计算选择主要通风机，并对通风系统进行了评价。

设计对矿井的瓦斯、自然发火等自然灾害提出了有效的防治措施，特别对自然发火的防治进行了详细的叙述和黄泥灌浆设计，可有效防治自然发火。

科技英语翻译部分探讨了计算机映射采矿中的断层，并举例说明！关键词：立井；长壁；抽出；突水；断层ABSTRACTThis design is made up of the ordinary part and the scientific English translation part.The ordinary part is the ventilation safety design of 2.4 Mt/a. The scientific English translate part is about the mining’s chasm in the post of the computer.Chensi colliery designing production capability is 2.4Mt/a, and the service time limit is 55 years. Its mining method is of the vertical shaft with single levels up and down hill. The level is on -520m. The set-up of the belt area applies single seam zone roadway layout. In the early period, we set up an integrated mechanized caving face with a tilt-wall mining. The mining applies Out of a ventilation shaft, the track Inclined Drift into the wind, Inclined Drift back to the wind belt. The mine’s ventilation mac hine is chosen according to the mine’s air quantity in easy and difficulty ventilation periods and the calculation of the mine’s ventilation resistance, and the mine’s ventilation system is evaluated.We put forward some effective measures to prevent the disasters of methane, natural fire and so on, and we especially dwell on the prevention of natural fire and the design of yellow mud grouting, and it has a good result.The scientific English translate part proclaims that the mining’s chasm in the post of t he computer and gives some examples.Key words: vertical mining; longwall; draw out; sudden inflow of water; chasm目录1 矿区概述及井田地质特征......................................................
