江苏金坛花山建筑用玄武岩矿地质特征及开采技术条件

Geological Characteristics and Mining Technical Conditions of Huashan Basalt Rocks for Building in Jintan, Jiangsu Province

在综合分析前人地质勘查、矿山开采资料和野外地质调查的基础上,对江苏省金坛市花山建筑用玄武岩矿地质特征和开采技术条件进行分析,认为花山建筑用玄武岩矿属新生代古近纪渐新世火山喷发(溢流)相,古近系渐新统三垛组下段是玄武岩的赋存层位,从上到下划分为三个岩性层,确定了矿区属于开采技术条件简单的Ⅰ类矿床。

Based on comprehensive analysis of predecessors’ geological exploration, mining data and field geological survey, the geological characteristics and technical conditions of the Huashan basalt for building in Jintan City, Jiangsu province are analyzed. It’s believed that the basalt mine used in Huashan is a Cenozoic Paleogene Eocene volcanic eruption(overflow) phase. The lower part of the Paleogene Oligocene Sancha formation is the occurrence of basalt, which is divided into three lithologic layers from top to bottom. It was determined that the mining area is a deposit(I) with simple mining conditions.
