以C#与ArcEngine的二次开发为工具,利用矿山已有钻孔数据,根据IDW法实现矿石储量估算。研究利用AE开发的IDW法在已知钻孔数据的情况下实现矿石储量估算与矿床矿石品位三维模拟分级显示。所用到的数学模型为球体模型,矿体模型为ArcGIS下建立的多片模型,主要建模软件为Google SketchUp。结果表明,利用AE开发的IDW法实现矿石储量估算的效率和精确度较高,开发难度和成本较低,开发周期短。系统矿石储量估算结果的平均反算误差为2.86%。
Taking the secondary development of C # and ArcEngine as a tool, the drilling data of the mine are used, and the ore reserves estimation is realized according to the IDW method. The IDW method developed by AE was used to study the estimation of ore reserves and the three-dimensional simulation of ore grades by the known drilling data. The mathematical model used is the sphere model. The orebody model is a multi-slice model built under ArcGIS. The main modeling software is Google SketchUp. The results show that the IDW method developed by AE achieves a higher efficiency and accuracy in estimating the ore reserves, and the development difficulty and cost are lower, and the development cycle is short. The average back-calculation error of the system ore reserve estimation result is 2.86%.
