Abstract

Mining operations in close proximity to dwellings and sensitive structures present challenges in terms of mitigating the undesirable effects of blasting while maintaining productivity and ensuring the safety of surrounding communities. This paper explores the application of advanced blasting techniques, including the use of electronic detonators and the splitting of total explosive charges, to address these challenges. A series of experimental blasts were conducted, comparing blasts conducted with and without splitting of holes, to assess the impact on ground vibrations. The results demonstrated significant reductions in vibration magnitudes when implementing controlled blasting practices with splitting techniques. The findings highlight the importance of total explosive charge in determining ground vibration magnitudes within the danger zone of mine workings. The use of electronic detonators provided precise control over blast sequencing, contributing to safer and more efficient mining practices. These advanced blasting methods offer a practical and innovative solution for conducting safe mining operations near dwellings and sensitive structures, ensuring compliance with safety regulations while sustaining productivity.
