摘　　要：原有露天矿中的数据采集点设置较为松散,导致常规的工程量计算结果精度较低,无法获取选定区域内的所有真实数据,研究基于密集点云方格网法的露天矿工程量计算方法。根据露天矿区的地势特点,多点定位采集并处理矿区数据,基于密集点云理论构建三维可视模型,以方网格法设计数据高程,分地点计算露天工程量,完成基于密集点云方格网法的露天矿工程量计算方法设计。实验结果:以实际验收的工程量为测试样本,本文方法能够在不同的地势样貌下进行密集点布控,所得工程量总数与实际值基本一致,具有实际应用意义。The setting of data acquisition points in the original open-pit mine is relatively loose,resulting in the low accuracy of conventional engineering quantity calculation results,and it is impossible to obtain all the real data in the selected area.This paper studies the engineering quantity calculation method of open-pit mine based on dense point cloud square grid method.According to the terrain characteristics of the open-pit mining area,collect and process the mining area data in multi-point positioning,build a three-dimensional visual model based on the dense point cloud theory,design the data elevation with the square grid method,calculate the open-pit quantities by location,and complete the design of the openpit quantities calculation method based on the dense point cloud square grid method.Experimental results:Taking the actual accepted quantities as test samples,this method can carry out intensive point control under different terrain features,and the total quantities obtained are basically consistent with the actual values,which has practical significance.
