摘 要:目前,在北京市域内非法开采矿产资源量计算工作中,普遍使用的计算方法有CASS软件DTM土石方计算法和垂直纵投影(水平投影)法,但在实际运用中这两种方法均存在一定缺陷,前者运算过程复杂,且难以查错,后者计算结果误差较大。利用3D Mine软件,计算北京市某村非法开采矿产资源量,计算结果经过相关部门证实与实际情况高度吻合,证明3D Mine软件计算结果真实可靠。该方法具有操作简便、易于查错、三维可视化、成果直观等优势。At present,two common calculation methods i.e.Cass DTM two-period earthwork calculation and vertical longitudi-nal projection(horizontal projection)are available for calculation of illegal mining mineral resources in Beijing.However,in practi-cal application,both methods have defects.The former is too complicated and difficult for error check,while the latter is not ac-curate and often produces wrong results.This paper uses 3D Mine software to calculate the amount of illegal mining mineral re-sources at a certain village in Beijing and systematically describes its technical principle and application process.The calculation re-sults have been confirmed and proved to be true,reliable and highly consistent with the actual situation.This method has the ad-vantages of simple operation,fast error-checking,3D visualization and intuitive results.
