DTM法在盗采矿产资源价值鉴定中的应用

DTM(Digital Terrain Models,简称DTM)土石方计算法,是指利用实测地形碎部点、特征点进行三角构网,用以计算给定区域内的土石方量。目前,该方法已广泛应用于工程测量领域的土方平衡和计算工作。在北京地区首次将DTM土石方计算法应用于非法开采矿产资源价值鉴定中,并以北京市顺义区木林镇非法开采建筑用砂石矿为例,通过方法应用、过程研究、计算分析等工作,准确计算了该地区建筑用砂石矿的非法开采量,与非法开采行为人供述的盗采方量吻合,得到了相关部门的认可。研究表明,DTM法能够准确计算非法开采矿产资源的数量,在非法开采矿产资源价值鉴定中具有良好的应用前景。

The Application of DTM Method in Identifying Mineral Resource Values by the Illegal Mining

DTM method (Digital Terrain Model) for earthwork calculation, refers to using the measured terrain points and feature points to establish triangulation network, and to calculate the earthwork volume for a given area. At present, this method has been widely used in the ifeld of engineering measurement earthwork balance and calculation. It’s the ifrst time that DTM earthwork calculation has been applied to identify mineral resource values by illegal exploitation in Beijing area, and take the illegal mining sand and gravel as a case in Mulin Town, Shunyi District, Beijing. By application method, process research and calculation analysis, we have accurately calculated the illegal mining volumes of sand and gravel in the area, which are accordant with statement ones by the illegal mining persons. The method has been recognized by the relevant departments. So DTM has the application prospects to estimate the mineral resource volumes by illegal exploitation and to identify their values.
