摘　　要：VCR模式为球形药包垂向漏斗后嵌类矿场技术,地底矿石洞也普及推广使用在天井挖掘作业中。笔者以某露天兼地底采掘金石七十米标高地表废弃石料场景为项目环境,透过实验参数明确爆破工程中的药包最理想埋进情况。生产实际表明,透过使用适度的凿孔设施,适度的先进工艺,VCR模式能够挖掘超高矿井,而且能够保证矿井工程进度。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.
