Item Parametric Analysis of Mine Bench Blasting using High Speed Video Camera(World Researchers Associations, 2025) Channabassamma, N.; Akhil, A.; Rama, S.V.; Kumar, T.A.; Sahana, P.This study presents a comprehensive parametric analysis of mine bench blasting through the utilization of high-speed video camera technology. Mine bench blasting is a critical operation in the extraction of minerals and understanding its parameters is essential for optimizing safety, efficiency and environmental impact. The research employs a high-speed video camera, specifically the S-Motion Model by AOS Technologies, Switzerland, capable of recording at 1000 frames per second. Here we carried out the sensitive parametric analysis like dependency of burden rock movement on ejection of stemming gaseous, stemming ratio, stemming height and total explosive charge using Proanalyst image processing software. Through the analysis, we identified key trends and correlations that contribute to control rock movement, stemming gas ejection and optimizing explosive charge distribution. This comprehensive understanding provides valuable insights for improving the overall effectiveness and precision of future blasting operations, thereby contributing to enhanced operational outcomes and safety in mining or construction activities. © 2025, World Researchers Associations.

This study focuses on optimizing the use of explosive energy to move the burden, thereby reducing reliance on mechanical methods. Effective blast design involves strategically utilizing energy within a blast hole, considering factors such as explosive type, quantity, detonation timing and blast hole geometry. Given the rapid nature of blasting, high-speed video cameras are employed to capture the blast progression on a millisecond scale, providing essential data for analyzing blast dynamics. This research evaluates the influence of blast design parameters, specifically the stiffness ratio (the ratio of bench height to the burden) and powder factor (the amount of explosive per unit volume of rock), on the movement of burden rock in a limestone mine. By examining these parameters, the study aims to optimize blast designs to achieve improved fragmentation, reduced fly rock and minimized ground vibrations, ultimately enhancing the efficiency and cost effectiveness of mining operations. © 2025, World Researchers Associations.
