Abstract

Mining activities are synonymous with the standard of life as well as the state of any nation. It results in both economic and uneconomic materials being generated. The uneconomic materials (wastes) are stacked at different places known as waste dumps. The stability of these dumps has been a major concern over the years. The problem becomes increasingly difficult with the reduced availability of land areas for dumping. The mechanized opencast mining methods have been extensively adopted by Indian mines to meet the increasing demand of coal which results into major disposal problem of large volume of waste material generated from mining operations in open -pit mines. The stability of dump slopes is influenced by a multiple of factors, including blasting vibrations. This research aims to analyze the impact of blast vibration on dump slopes through field investigations and parametric study by using numerical modeling, utilizing the Flacslope software. Our findings indicate that, no explicit dump failures were observed in the study area, an increase in peak particle velocity leads to a reduction in the slope’s Factor of Safety, as evidenced by our parametric study.
