VCR mode is a vertical funnel embedding mining technology for spherical drug charges,and underground ore tunnels are also widely promoted and used in courtyard excavation operations.The author takes the scene of an open-pit and underground mining of abandoned stone materials at an elevation of 70 meters as the project environment,and through experimental parameters,clarifies the optimal burial situation of the explosive package in the blasting project.Production practice has shown that through the use of moderate drilling facilities and advanced technology,VCR mode can excavate ultra-high mines and ensure the progress of mine engineering.
