吉林省桦甸市隆兴铁矿深部勘探及矿体地质特征

Deep exploration and geological features of Longxing iron minein Huadian City, Jilin Province

本次工作在充分搜集、分析、研究以往地质勘查及矿山开采资料的基础上,以钻探、坑探、槽探工程为主要手段,辅以必要取样测试,对已有矿体进行系统控制,详细查明矿体的规模、形态、厚度、品位变化情况。通过本次勘探共圈出13条矿体,矿体长32~500 m,控制矿体斜深13~235 m,厚度1.27~6.17 m,矿体倾向为180°~200°,矿体倾角53°~80°,矿体赋存标高240~500 m。本矿床属(火山)沉积变质型铁矿。矿石结构构造以粒状变晶结构、片麻状构造为主。矿石自然类型为石英型磁铁矿;矿石工业类型为需选磁铁矿石。

Based on the full collection,analysis and study of previous geological exploration and mining data,this work takes drilling,pit exploration and trenching exploration as the main means,supplemented by necessary sampling and testing,systematically controls the existing ore bodies,and carefully identify the changes in scale,shape,thickness and grade of the ore bodies.Through this exploration,a total of 13 ore bodies were delineated,with length 32500m,the oblique depth of control bodies 13235 m,thickness 1.276.17 m,tendency 180°200°,dip angle 53°80°,and occurrence elevation 240500 m.The deposit belongs to the(volcanic)sedimentary metamorphic type iron ore.The ore structure is mainly composed of granular metamorphic structure and gneissic structure.The natural type of ore is quartz type magnetite,while the industry type is magnetic ore that needs to be selected.
