文档介绍：摘要
本设计包括三个部分:一般部分、专题部分和翻译部分。
。陈四楼煤矿位于河南省永城市,井田南北长约12km,东西宽约6km,勘探面积约72km2。,,这两层煤从厚度和赋存条件是可采煤层。井田工业储量为30396万t ,矿井可采储量20467万t,。井田开拓采用立井单水平开拓,设置辅助水平。采煤方法采用一次采全高综合机械化采煤,工作面布置为带区式布置。大巷布置为轨道大巷进风兼辅助运输,皮带大巷运煤兼回风。矿井通风方式为中央并列式,采煤工作面采用U型通风方式,掘进工作面采用局部通风机通风。
,,困难时期为1168Pa。, m2。,其能满足矿井对风量的要求。
综上所述,陈四楼矿通风系统简单,合理,稳定,满足通风要求,抗灾能力强。
专题部分题目是综合防尘技术在陈四楼的应用,探讨了煤层注水以及在水中添加活性剂和使用磁化水改善煤层注水效果,采煤机外喷雾系统,顶板支架喷雾系统,进、回风顺槽的防尘措施,掘进面的防尘措施以及各种喷嘴的选择和安装等内容。通过研究,为陈四楼矿的防尘工作和防止瓦斯突出提出了理论依据,极大的增强了煤尘事故预防的准确和可靠性。
翻译部分主要内容为矿井通风空气的流动特点。
英文题目为:Characteristics of coal mine ventilation air flows
关键词:陈四楼矿井; 新井通风设计; 综合防尘; 空气流动特点

ABSTRACT
This design consists of three parts: The general part, the special part and the translation part.
The productive capacity is million tons per year. The Chensilou minefield lies in the special area of Yong Cheng city, Henan province. Total area of the mine is 72 km2. The boundary of the minefield runs 12 km on north south and 6 km on west east on average. There are two main seams—the third layer with thickness of meters and the second one with thickness of meters. According to the thickness and deposit, the two coal layers are able seams.
The industrial storage of the mine field is 30396 million ton, the reserves exploitable in the whole mine field is 20467 million ton,and it’s service life is 87 years, with only one working faces is used in the mine. One standards development are used in the Mine shaft pioneering,with subinclined shaft Coal mining use a high-wide integrated mechanized mining,with face layout of the belt-type track roadway with the airflow into are mainly used to transported the coal while the belt roadway are used to the auxiliary transport with the return of method of whole mine ventilation is central juxtapose ventilation ventilation
