1、摘 要 设计矿井井田面积为8.759km2,可开采的11-1号、11-2号和14号煤层设计矿井出产能力为2 mt/a,矿井面积居中,年产量较高,煤层赋存条件较好,倾角较小,变化不大,平均煤层倾角为3。根据井田地质资料以及地表地形图的详细研究,井田开拓决定采用主副斜井,在井田中央布置主副井。由于煤层倾角较小,采用盘区划分,布置三条大巷,采用上下山布置盘区工作面,工作面采煤工艺使用倾斜长壁采煤法,放顶煤开采,综合机械化采煤。井田中部有断层群发育,无陷落柱和村庄,煤田水文地质条件良好,涌水量不高,瓦斯含量低,采用的是中央并列式的矿井通风方法,全面满足矿井的通风条件。关于矿井的重要运输设备、辅助运输设
2、备、排水、通风、排矸系统进行设计和设备的选型。查阅诸多专业文献和国内著名的一些现代化矿井,借鉴其经验,力争设计出安全、经济、高产、高效、符合生产要求的现代化矿井。关键词:斜井、放顶煤、走向长壁、AbstractDesign of the mine field area of 8.759 km2, recoverable, 11-11-1 2 and 14 # coal seam mine production capacity of 2 mt/a design, the mine area of middle and annual output is higher, the occurrenc
