Research on closed shell envelope voxel modeling of open-pit coal mine based on ternary DEM
As the traditional geological model is limited by its own structural properties and Boolean operation efficiency,the generation of mining model can not meet the needs of large-scale material planning problems in open pit mine,the mining block model and mining model are defined,and an open-pit coal mine closed shell envelope voxel modeling method based on ternary DEM,that is the top,bottom and side DEM modelling,and after curing the coal and rock the ternary DEM can generate the corresponding closed shell envelope voxel model.The model is between entity model and the block model,which is able to ensure the calculation quantity accuracy and high Boolean operation efficiency at the same time,thus to achieve fixed and directional dimensions and structural cutting in reality.Based on traditional computational models,specific structural definitions can be used to enrich technical indicators such as stripping procedures and process parameters,customize exclusive mining models,and better serve problems such as open-pit mineral material flow planning and dynamic optimization of stripping production plans.
