摘要
贵州丹寨县白元—翁垴地区玻璃用砂岩矿赋存于泥盆系蟒山群第二段内,属于浅海及滨海相机械沉积的石英砂岩矿床,受层位控制明显。综合矿石化学成分及矿物粒度级别进行判别,矿石品级应属于平板玻璃用硅质原料四级品。通过矿床开采技术条件研究,认为矿床属于以工程地质环境地质问题为主的复合问题的中等类型矿床(Ⅱ-4型)。露天开采方式支护成本等相对较低,具有较高的经济价值。
The sandstone mine for glass in Baiyuan-Wengnao area of Danzhai County,Guizhou Province is located in the second member of the Devonian Python Mountain Group,which belongs to the shallow sea and coastal facies mechanical sedimentary quartz sandstone deposits,and is obviously controlled by the horizon.Based on the chemical composition of the ore and the grade of mineral particle size,the grade of the ore should belong to the fourth grade of siliceous raw materials for flat glass.Through the study of the technical conditions of ore deposit mining,it is believed that the ore deposit belongs to the medium-type ore deposit(type II-4)with composite problems mainly engineering geology,environmental geology.The cost of support by open-pit mining is relatively low,which is of high economic value.
