低空倾斜摄影在矿山无证开采调查中的应用

Application of Low-altitude Oblique Photography in Unlicensed Mining Survey of Mine

在调查区域进行无人机倾斜摄影高精度三维建模,计算采矿前后的地表变化差异,获取矿山无证开采的矿产资源方量;并结合矿区岩石样本岩性鉴定和密度检验结果,计算矿山无证开采的矿产资源储量,对开采行为和地表破坏程度进行评估。结果表明,该工作方法对于矿山无证开采调查实施具有一定的可操作性和参考意义。

In this paper,we introduced a method of low-altitude oblique photography technique to conduct unlicensed mining survey of mine.Through UAV oblique photography and high precision 3D modeling of unlicensed mining areas in mines,we calculated the differences in surface changes before and after mining to obtain the amount of mineral resource of unlicensed mining.Then,we used the lithology identification and density test of the rock samples in the mining area to calculate the mineral resource reserves of the unlicensed mining of mines,and assessed the mining behavior and surface damage.The result shows that the work efficiency can be significantly improved.This study can provide certain operability and reference significance for the implementation of the unlicensed mining survey of mine.
