1、内蒙古科技大学本科生毕业设计说明书题目:易顺煤矿9#煤层矿井开采设计(150万t/a)学生姓名：闫占飞学号：1272101112专业：采矿工程班级：采矿12-1班指导教师：郑文翔评阅人：成绩：摘要本设计为易顺煤矿9#煤层150万t/a开采设计。全部设计包括矿区概述及井山地质特征、设计储量及开采年限、井田开拓方案、采煤方法的选择、采区巷道布置、回采工艺设计、通风供电及排水、安全技术措施等。井田煤层厚度为平均12.71m,采区倾角为0〜5°，井设计储量为93.31MI,生产能力为150力-t/a,瓦斯涌出量较低，属于低瓦斯矿井，地质构造较为简单，无明显褶皱断层，
2、交通便利。井田开拓方案为斜井开拓，主斜井为大倾角胶带运输机运煤，副斜井采用无极绳单钩牵引矿车运输作为辅助运输，井田总共分为两个带区，首采区工作面长度为157m,开采顺序为前进式，采煤方法为综采放顶煤，工作面釆用双巷制。带区采用四六制作业，三班采煤，一班检修，主产人数为66人，一天循环三刀,生产每一循环一刀，截深为0.8m,采煤高度为3.5m,放顶高度为10m,矿井总风量为50.66m3/s,通风方式为抽出式。机型选型为FBCDZ-10-N030D关键词：斜井开拓；带区式开采；综采放顶煤；前进式，双巷布置；四六制;Thedesignistheexploitat
