大型露天磷矿数字矿床系统

Digital mineral deposit system of large open phosphorite mine

"数字矿山"作为信息时代的必然产物,在矿业中发挥出越来越大的作用,通过数字化矿山建设实现矿产资源储量的可持续管理,是矿业发展的目标和方向.依据云南磷化集团昆阳磷矿地质报告、地形地质图、剖面图等相关资料,研究昆阳磷矿矿床分布空间关系,采用DIMINE矿业软件,建立不同数据信息表,并进行错误校正,然后依次将上述信息导入DIMINE软件,生成钻孔地质数据库.利用地形地质图和钻孔数据库建立昆阳磷矿四采区的地形模型、三维实体模型,通过块段模型,并对不同品级矿石赋予各块段不同的体重值,运用距离幂估值地质统计法进行储量估算,实现资源储量估值.

＂Digital mine＂as the inevitable outcome of the information age,it plays a more and more important role in the mining industry,the sustainable management of the mineral reserve is realized through the construction of the digital mine,which is the goal and direction of mining development.Based on the rock geological report,figure of terrain geological,profile and other relevant materials of Kunyang mining,Yunan phosphorite group Co.,Ltd,the spatial relations of Kunyang phosphate ore deposit distribution were researched and different data information tables were set up,the rock geological database was generated by inputting those information tables to DIMINE software.Then the terrain model and the three-dimensional entity model were established by the figure of terrain geological and rock geological database.Through establishing the block model and giving the different grade ore with different weight,the geological statistics method of power distance valuation was used to estimate the reserve,which realizes the resources valuation.
