2、ChongqingUniversityMay2014[在此处键入]中文摘要摘要这次毕业设计的题目是水银洞金矿年产30万吨地下开采初步设计。目前控制的共计23个矿体,Ⅲc、Ⅲb、Ⅲa、Ⅱf、Ⅰa为最主要矿体。矿体呈缓倾斜分布。倾角大约在50-100。在对四川省金河磷矿为期两周的毕业实习基础上,以金河磷矿为蓝本,根据老师所给的水银洞金矿的矿床地质等地质条件和现有生产设备等技术条件,按照国家规程规范等设计文件要求,结合自己所学的知识和所掌握的信息,设计出了比较完整合理的开拓方案。设计中采用比较新式的单一井筒开拓(箕斗罐笼综合提升);采用两翼对角式通风,这样可以减小工程量,并且通风效果也好。
3、金矿主要采用上向分条充填采矿方法,有较高的回采率。通过对经济技术进行比较过后,其设计的开拓方案、采矿方法及相关设备均能满足矿井年产30万吨的开采要求。关键词:水银洞金矿,矿井初步设计,近水平矿体,箕斗罐笼综合提升,上向分条充填采矿方法I目录ABSTRACTThetopicofthisgraduationdesignisThepreliminarydesignofUndergroundgoldmininginSHUIYINcavitywhoseAnnualoutputisof300000tons.Thetotalnumberoftheorebodysthatincontrolis23i
