1、 I 摘摘 要要 本设计是根据七星煤矿的实际情况进行的初步设计。设计的井田面积约为 13 km2，主采煤层 2 层，即 16 号和 21 号煤层，平均倾角 12 ，煤层平均厚度 2.7 m，整体井田地质条件比较简单，相对瓦斯涌出量为 18.48m3/t，井田涌水涌 出量为 462.68m3/h。设计采用立井多水平开采的开拓方式，采用采区式准备方 式，采用走向长壁采煤方法，综合机械化的回采工艺，全部跨落法处理采空区。 设计生产能力 0.9Mt/a，服务年限为 56.44 a。矿井通风方式为两翼对角式，通 风方法为抽出式。 本设计主要对矿井开拓方式、准备方式、采煤方法进行了初步设计，对局 扇和主扇
2、进行了设备选型计算，并对矿井安全技术措施和环境保护提出要求， 完成整个矿井的初步设计。在设计过程中，尽量采用先进的技术和设备，提高 矿井的机械化装备水平和生产效率。 关键词关键词: 开拓方式；通风系统；机械化 II ABSTRACT The design is a preliminary design of the Qixing coal mine based on the real situation. The area of mine designs about 13km2 , having two main layer, 16# and 21#, about 12 degrees, 2.
3、7 m thick on average, and the whole geological structure is relatively simple. The gas flow-volume was about 18.48m3/t, and the volume of water is 462.68 m3/h. The design adopts the development way of vertical shaft multi-level mining, using the mode of panel type, the long wall mining coal method,
4、and the synthesis mechanization returns picks the craft, all cross falls law processing to pick the depletion region. The mines designed production ability is 0.9 Mt/a, and with a mine life of 56.44 a. Its ventilative way is boundary ventilation and working method of fan is exhausting. The design ha
5、s conducted the preliminary design of pioneering way, preparation methods, exploitation of mining method. And the equipment selection calculation of local fan and main ventilator, as well as mine technical safety measures and environmental protection. In the design process, the use of advanced techn
6、ology and equipment improves the mechanization level and mine production efficiency. Keywords: explore ways; ventilation system; mechanization 1 目 录 摘摘 要要 I ABSTRACT .
