Abstract
In the process of open-pit coal mine mining,the calculation of ore body and tailings reservoir volumes is heavy,with low efficiency,and the calculation of irregular accumulated ore bodies has low accuracy and is difficult.To address these issues,this paper presented a method for calculating mining and stripping volumes in open-pit coal mines by combining Web graphics library(WebGL)and triangulated irregular network-generalized tri-prism(TIN-GTP).The method utilized high-resolution realistic three-dimensional(3D)data and combined WebGL with the TIN-GTP algorithm to precisely and efficiently calculate the mining and stripping volumes in open-pit coal mines.By taking an open-pit coal mine as an example,the highest elevation,area,and volume of the accumulated ore body in the open-pit coal mine were calculated at different sampling intervals of 2,1.5,and 1 m.Moreover,the TIN-GTP method was compared with the fine grid method and digital terrain model(DTM)method.The results show that this method can effectively calculate the mining volume in open-pit coal mines,and it has higher efficiency and accuracy than common volume measurement and calculation methods,providing a reference for engineering amount verification and estimation in mining areas.关键词
