山西大同大学 本科生毕业设计 中文题目 英文题目：entilation Design and Mine Dust Prevention of Dongzhouyao Mine 8-1 Coal Seam 学 院： 煤炭工程学院 姓 名： 学 号 100810021117 专 业： 班 级：指导教师： 职 称： 完成日期： 2014 年 月 日关键词：ABSTRACT ?? With the development of coal industry, safety production has become the significant part .In order to keep the?safe production of coal mine , the design is of great importance. According to the actual situation of Dongzhouyao, the safety production technology was applied to the Dongzhouyao 8-1 seam make the ventilation design and specific design. ????The basic task of the mine ventilation design is to create a safe,reliable, advanced? and economic system. The mine would use the? method of central compond-like ventilation .With the increase of mining areas, the modality would transit to the partition type ventilation system by draining out mechanically.First of all, the required air volume of mine was calculated. Combining the calculation of the resistance when? the mine ventilation was in an easy and difficult period with the fan characteristic curve.Then,the mine fan and motor would be selected out.Besides, mine ventilation structures was required to lay out. ????In view of the dust damage from the Dongzhouyao 8-1 seam, the design should demonstrate three aspects - the dust prevention , explosion prevention and flame prevention. ? ? Keywords: ventilation design ; special design ; ventilator ; ventilation structures. 目 录 1 矿井概况 1 1.1地理位置及交通概况 1 1.1.1井田位置及交通情况 1 1.1.2周边小窑情况 2 1.2井田地质构造 2 1.2.1井田地层 2 1.2.2井田构造 2 1.2.3煤层赋存状况 3 1.2.4煤质 4 1.2.5水文地质条件 4 1.2.6煤层顶底板岩性特征 5 1.2.7瓦斯 5 1.2.8煤的自燃与煤尘爆炸性 5 2 井田开拓 7 2.1井田储量 7 2.1.1井田境界 7 2.1.2矿井资源/储量 8 2.1.3矿井设计生产能力及服务年限 10 2.2井田开拓 10 2.2.1井口及矿井工业场地 10 2.2.2井筒形式的选择 11 2.2.3开拓部署 13 2.2.4井筒 19 2.2.5大巷布置及支护 20 3 采区布置及开采方法设计 21 3.1采区划分及接替 21 3.1.1采区巷道布置 21 3.1.2巷道断面及支护形式 22 3.1.3采区划分与接替 23 3.2采煤方法 24 3.2.1采煤方法选择 24 3.2.2工作面产量核定 24 3.2.3回
