影像分区法在矿山覆盖层资源量估算中的应用

The Application of Image Zoning Method in Estimation of Mine Overburden Resources

数字正射影像(DOM)具有信息丰富、直观、分辨率高、方便使用等特点,为矿山覆土层资源量估算提供了新的途径。文章介绍了一种借助DOM估算矿区覆盖层资源量的新方法—影像分区法。影像分区法结合矿区DOM对露天矿山覆土层进行分区,然后采用平均值法进行分区计算,估算矿山覆盖层资源量。该方法具有简单、快速、便捷的特征,弥补了传统覆土层资源量估算方法计算烦琐、工作量大、无法反映土层分布特征的弊端。

Digital Orthophoto Map(DOM)has the characteristics of rich information,intuitiveness,high resolution and convenient use,which provides a new way for the estimation of mine overburden resources.This paper introduces a new method of estimating the amount of overburden resources in mining area by means of DOM-image zoning method.The image zoning method combines the DOM of the mining area to partition the soil overburden of the open-pit mine,and then uses the average value method to calculate the partition to estimate the amount of mine overburden resources.This method is simple,fast and convenient,which makes up for the disadvantages of the traditional method of estimating the amount of overburden resources,such as cumbersome calculation,heavy workload and inability to reflect the distribution characteristics of soil layers.
