摘要
从空间模型入手,提出了一种基于空间模型集成模式的固体矿产勘查储量估算方式。该方式包括:将序列断面模型与传统储量估算法中的剖面法和地质块段法相结合;将实体、块体模型与地质统计学储量估算法相结合;将断面—三角网模型与矿体任意中段图的生成相结合;将DEM模型与矿区模拟等结合研究。形成多种储量估算方法并行并重,并对矿体形态和被估区域实现三维可视化模拟,直观表现估算成果。此法既满足了国内传统储量估算方式的需求,又结合了国际上通用的地质统计学估算法。运用原型系统在全国多个矿区进行矿产勘查储量估算及可视化模拟,获得了较好的估算效果。
Start with spatial models,the authors propose a solid mineral reserve estimating method based on integration mode of spatial data models.The method includes the following：（1） the series section model with traditional reserve estimating methods,（2） volume and block model with the geological statistic method of reserve estimating method,（3） Triangular grid model with random mineral mesial chart,（4） DEM with mineral area simulating,which integrate multi-solid mineral reserve estimating method as a whole,implementing the mineral configuration and estimated diggings 3D visualization.The method doesn’t only satisfy internal traditional reserve estimating methods,but also combines international geological statistic method of reserve estimating.The prototype system has conducted in several mineral areas in country with 3D visualization,receiving satisfactory effect.
