摘要
矿山露天开采资源量计算通常采用断面法,同时也可以用测量中的土石方法(方格网法、DTM法)计算露天开采资源量。以贵州省露天矿山储量动态监测为基础,建立断面法和方格网法、DTM法计算模型,分析影响断面法和方格网法、DTM法精度的因素,采取相应措施提高计算精度。通过对比分析断面法、方格网法、DTM法的特点,确定在各种复杂地形条件下选用更为合理的计算方法。
The calculation of mine open-pit mining resources usually adopts the section method,and the open-pit mining resources can also be calculated by the earth-rock method(square grid method,DTM method)in the measurement.Based on the dynamic monitoring of open-pit mine reserves in Guizhou Province,the calculation method of section method,grid method and DTM method is established.The factors affecting the accuracy of section method,grid method and DTM method are analyzed,and corresponding measures are taken to improve the calculation accuracy.At the same time,by comparing and analyzing the characteristics of the section method,the grid method and the DTM method,it is determined that more reasonable calculation methods are selected under various complex terrain conditions.
