| Summary: | The article discusses the methods of calculating the drilling and blasting scheme and constructing a drilling grid, manual and automatic calculation options are compared. A method for automatically constructing a drilling grid based on laser scanning is proposed. Moreover, the proposed method can be implemented using cheap equipment - a laser rangefinder and an Arduino microcomputer. Based on the data of the laser rangefinder with openCV and SciPy libraries, a polygonal 3D model of the face is built. The transfer of the drilling grid to the 3D model is implemented using the bilinear interpolation algorithm. The constructed polygonal model can be improved by making changes to the construction algorithm, since it is developed by the authors and can be further developed. The simulation model is created in Anylogic software and shows the drilling process taking into account the previously calculated drilling pattern. The proposed models can be used as a basis for further research and software development.
