Technological schemes of blasting operations for ensuring stability of Amantaytau quarry slopes

Abstract

This article presents a comprehensive study conducted at the Amantaytau Quarry, focusing on enhancing slope stability through advanced blasting techniques. The research includes theoretical analyses, laboratory experiments, and geomechanical assessments to optimize quarry face parameters and ensure long-term stability. Key findings involve developing specialized blasting technologies for extracting pre-contour zones to reduce dynamic loads on quarry faces. The study also zones the quarry based on stable slope angles, providing crucial insights for the project contour. Achieving recommended slope angles requires specific drilling and blasting methodologies to configure benches into their ultimate positions. Quantitative and qualitative patterns of rock fragmentation have been analyzed to determine the width of the pre-contour zone, charge quantity, specific explosive consumption, and parameters for explosive borehole placement. These methodologies are crucial for ensuring safety and longterm stability. The article concludes with recommendations for practical applications, emphasizing the need to reevaluate zoning boundaries and parameters when modifying the project contour. This research contributes valuable insights to quarry engineering, providing a basis for implementing efficient and safe blasting practices for improved slope stability.
