1、摘 要 本设计所选的题目为山西省阳泉市上社二景煤炭有限责任公司的初步设计,根据山西省阳泉市上社二景煤炭有限责任公司提供的井田概况和地质特征资料。井田概况包括井田境界;地表的交通位置以及自然地理和水源、电源的供应情况。地质特征资料包括地层;地质构造;煤层及煤质;煤层顶、底板情况及煤层的瓦斯、煤尘、煤的自燃性;以及矿井的水文地质情况。此次设计的目的是其目的运用大学阶段所学的知识联系矿井生产实际进行矿井开采设计,并就本专业范围的某一课题进行较深入的研究,以培养和提高学生学习分析和解决实际问题的能力,是学生走上工作岗位前进行的一次综合性能力训练,也是对一个未来采矿工程高级工程技术人才的基本训练。设计时
2、应以当前煤矿开采发展的趋势和方向,结合本煤矿的特征以综合机械化打采高开采为首选采煤方法。并合理的布置开拓巷道和工作面,以简化采煤生产系统提高煤炭的利用率。此次设计需要解决的专题是高瓦斯易自燃煤层的开采,要求我们需要在采区巷道的布置上及以后的生产管理上采取特殊的措施,以实现矿井的安全生产。该矿井的设计生产能力为60万t/a,采用两个水平分组开采,采用条带式布置后退式开采一次采全高,采用完全垮落法管理顶板。采用综合机械化开采。设计过程中我们对矿井的各个系统又有了一次比较全面的认识和了解,同时在老师的辅助和帮助下也解决了一些接近的实际的问题。使我们在掌握专业知识的同时也提高了自己以后在现实工作岗位上
