摘要
爱景山锶矿是我国首次发现的火山热液改造型锶矿,无同类矿床可类比,给地质勘探工作带来一定难度。根据矿床特征,参照《苏联矿产储量分类规范》及稀有、稀土金属和其它有关规范,由江苏省石化厅、江苏省储委、化工部地质勘探公司、化工部设计研究院。
Aijinshan strontium deposit located in Lishui County, Jiangsu Province,is a large scale of rare metal deposit. It is composed of four orebodies, among them No. Ⅱ is a major exploration orebody. The deposit is characterized by a simple shape, small variation in ore grade, perfect continuity and great variation of orebody thickness. It belongs to a deposit with stable, steep-dipping distribution and complex internal structure. So far, only C grade reserves has been explored without B grade reserves in the deposit. The author consider that it is rational and available to carry out a new exploration network to enhance grade of reserves, based on the variation characters of orebody, correlation between reserves calculation of different networks and experience of exploration and mining in part sections. According to concerning exploration standard, some B grade reserves should be explored in the district. Therefore, the author indicate that the exploration network of 25×25 meters should be used to explore B grade reserves, network of 50×50 meters to explore C grade reserves and 100×100 meter to explore D grade reserves.
