Research on time–frequency characteristics of electromagnetic signals from coal and rock blasting based on DBO-VMD filtering

Research on time–frequency characteristics of electromagnetic signals from coal and rock blasting based on DBO-VMD filtering

In shaft mining, conventional vibration monitoring of blasting operations is often affected by environmental factors and system limitations, complicating the extraction of coal–rock rupture signals. This paper explores the use of electromagnetic radiation signals for blasting monitoring, introducing...
