河 南 理 工 大 学采矿工程专业（本科）毕业设计说 明 书姓 名：学 号：学 院：河南理工大学能源科学与工程学院班 级：设计题目：大柳塔煤矿采矿专项初步设计指导教师：职 称：副教授二零一六年六月摘要本设计的井田面积为20.02km2，设计生产能力1.2Mt/a。井田内煤层赋存比较稳定，煤层倾角在1°-3°，属于近水平煤层，平均煤厚4.38m，地质条件比较简单，在井田范围内断层稀少，仅有的几个小断层也分布在井田边界附近，所以视井田内无断层。瓦斯和二氧化碳含量相对不高，相对瓦斯涌出量4.01m3/t·d,正常涌水量100.95m3/h,涌水量比较小。根据实际的地质资料情况进行井田开拓和准备方式的初步设计，该矿井对开采的22煤层决定采用平硐开拓单水平盘区式划分开采，设计采用走向长壁后退式全部垮落综合机械化一次采全高的采煤方法。并对矿井运输和通风等系统的设备进行选型计算、提出矿井安全技术措施以及完成整个矿井的初步设计。矿井全部实现机械化，采用先进技术和借鉴高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。关键词：平硐　 盘区式 走向长壁 综合机械化Abstract The design of the field area of 20.02 k㎡, design production capacity of 1.2 Mt/a. Within the field of coal seam occurrence is stable, dip Angle of coal seam in 1 ° ~ 3 °, belong to the nearly horizontal coal seam, the average coal thickness 4.38 m, geological condition is simpler, within the scope of the field fault rare, one of the few small fault distribution near the border of the field, so no fault in the visual field. Methane and carbon dioxide content is relatively high, the relative gas emission 4.01 m3 / t, d, normal water inflow 100.95 m3 / h, water inflow is small. According to the actual geological data of field development and preparation of preliminary design, the 22 of mining coal mine decided to adopt adit development level of single panel type classification mining, design to adopt longwall retreating all comprehensive mechanized caving mining overall height of the coal mining method at a time. And the mine transportation and ventilation system of selection of equipment, mine safety technical measures are put forward, and complete the preliminary design of the mine. All mine mechanization, the use of advanced technology and based on the experience of the modern mine high yield and benefit, achieve a high yield an efficient mines so as to achieve good economic and social benefits.Keywords:adit panel mining strike longwall comprehensive mechanization　　　前言经过为期一个月的毕业实习，对矿上的生产系统和具体的生产流程有了一个全面的认识，通过接下来的毕业设计可以让我们对所学知识有一个总结，同时也可以加深我们对矿井的认识。本
