    资源描述:
    摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为陈四楼煤矿 1.8Mt/a 新井设计。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。此井田中只有 3 煤层厚4.18m,2 煤层厚 2.95m,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,矿井服务年限为 87.4 年。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。矿井总进风量为 3782.16m3/min,通风阻力容易时期为 820.8Pa,困难时期为1168Pa。矿井巷道等积孔容易时期为 2.62m2,困难时期为 2.18 m2。通过计算决定选用 2K60No.24 轴流式通风机,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ABSTRACTThis design consists of three parts: The general part, the special part and the translation part.The productive capacity is 1.8 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 4.18 meters and the second one with thickness of 2.95 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 extension.The Coal mining use a high-wide integrated mechanized mining,with face layout of the belt-type layout.The 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 airflow.The method of whole mine ventilation is central juxtapose ventilation system.The ventilation of the dead-end working places is the application of the auxiliary ventilation by the auxiliary fans. The total amount of wind required is 3490 m3/min, and the ventilation resistance 386.7 Pa at easy period while difficult period of 602.7 Pa. The equivalent orifice is 3.26 m2 when easily period whlie difficult period is 2.62m2.So I choose the 2K60No.24 with the axial-flow as the main fan which can meet the need of the whole airflow of the requirement.In summary, the Chensilou mine ventilation system is simple, reasonable, stable and meet the ventilation requirements of fighting ability.The special part is the integrated dust of the application in Chensilou mine .The content is to discusse coal injection, add active agent in the water and use water to improve coal injection magnetic effect, the shearer with spray system. the spray the roof stent system,the measures of in and out wind Gate, the excavation of the dust and various measures of the nozzle selection and installation. Through research, for the Chensilou mine dust and gas outburst to prevent a theoretical basis, greatly enhanced the accuracy coal dust accident prevention and reliability.The translation part is
