【摘要】 基于谦比西铜矿矿床结构和生产情况,运用地质统计学的方法对矿区的铜品位分布情况进行了研究,分别得到矿体垂直方向,矿体倾向方向,矿体走向方向铜品位的变异函数,该函数呈几何各向异性,各向异性比分别为1∶21.17∶15和1∶15.7∶17.14,反映矿体品位在垂直方向相关性差。该模型为以后的规划、设计和生产提供了理论依据。更多还原

【Abstract】 In view of Chambishi Copper Mine’s deposit structure and production conditions,study was made on the copper ore grade distribution in the mining area using geological statistics.As a result,variant functions of copper grade in the orebody’s vertical direction,dip direction and strike direction respectively were obtained.They are of geometric anisotropy,with the anisotropic ratio being 1∶21.17∶15 and 1∶15.7∶17.14 respectively,indicating a poor correlativity of the orebody grade in the vertical direction.This grade distribution model provides a theoretical basis for the future planning,design,and production.更多还原
