| 摘 要： | 依据河南省鲁山—宝丰韩梁地区铝土矿的地质特征,利用Surpac 6.3矿业软件建立了该矿区的地质数据库及地层、矿体、断层和地表模型,形象表达了矿区的地形地貌和矿体的产状及空间关系。推断出矿床形成的环境和成因,应用块体模型和距离幂次反比法对矿体的品位分布和资源量进行了动态估算,表明块体估算资源量的方法可靠准确,提高了储量估算的效率,为勘查工作提供了可靠的参考和科学依据。

| Abstract: | The authors established a 3D geological database and a surface model for strata,ore,faults for the mine,according to the geological characteristics of Lushan-Baofeng Hanliang area in Henan Province and the use of Surpac 6. 3 mining software. It visually expressed the mining area topography and the ore body occurrence and space relations. According to geological data and geological models,it inferred the environment and the genesis for the deposit. The ore grade distribution and resources were dynamic estimated by the block model of the ore and IDW method and compared with the traditional resource estimation technology,indicating IDW method for estimating resource was reliable and accurate to improve the efficiency of reserves estimation. |
