1、内蒙古科技大学本科生毕业设计说明书(毕业论文)题目:内蒙古永智煤炭公司3煤层地下开采初步设计摘要矿井生产,其主要特点是地下作业,工作环境艰苦,自然条件复杂,通风和安全措施显得尤为重要。各煤田所处的地理位置不同,煤层地质条件多种多样,开采方法也就多种多样。本设计是在永智煤矿原始地质条件下作的矿井初步设计,设计内容包含:井田概况及地质特征、矿井开拓、通风设计、矿井安全技术措施,以及专题—采煤工作面瓦斯综合治理等方面。井田概况主要包括矿区的地理、地形和交通;矿井的地理位置、井田范围;矿区的气象条件、地震烈度、电源和水源的概
2、况;井田地质特征、煤层及煤质概况以及水文地质条件概况等。矿井开拓分别论述了主井、副井位置选择、采区的划分、水平的划分以及开采顺序、采区的布置及装备、各巷道的布置等。通风设计主要包括矿井通风系统的选择、矿井所需风量的计算及分配、全矿井前期、后期的通风阻力计算以及对通风设备的选择等。安全技术措施包括井下瓦斯预防、顶板管理、水灾预防、火灾预防、煤矿爆炸的预防及粉尘防治措施等。关键词:矿井;开拓开采;通风;安全;瓦斯综合治理。ABSTRACTThecoalfieldtothegeographyandvariedgeologi
