Mapping Blasting Vibration Distribution in Coal Mining Using Kriging Interpolation

Summary/Abstract: Coal mining has a significant impact on the environment and surrounding society. One of the main impacts of open-pit mining activities is vibrations generated from blasting, which have the potential to damage the ecosystem and building structures around the mine site. This research aims to analyze the distribution of blasting vibrations in the mining environment using the Kriging geostatistical method. The Kriging method was chosen to map the vibration distribution and produce zoning based on the level of vibration risk to the environment and surrounding society. The data used included vibration measurements from 25 blasting operations taken from 2717 drill points over one month. The results showed that the Kriging method successfully predicted vibration distribution well, producing a zoning map that divided the area into a safe zone, cautious zone, and hazard zone. The cautious zone is characterized by very high vibration intensity, which has the potential to damage building structures and endanger human health. These findings provide important insights for mine management in more effective risk mitigation and planning efforts to minimize the negative impacts of blasting vibrations on the environment and society.
