Predicting Blast-Induced Ground Vibration in Open-Pit
2021712 Blast-induced ground vibration (GV) is a hazardous phenomenon in open-pit mines, and it has unquestionable effects, such as slope instability, deformation of structures, and changing the flow direction of groundwater. Therefore, many studies in recent years have focused on the accurate prediction and control of GV in open-pit mines.

Monitoring and control airblast overpressures in an open pit coal mine
202121 Abstract. Besides ground vibrations, air transmitted vibrations or airblast overpressures (AOp), are also generated during blasting operations. Mae Moh coal mine, Thailand, has been concerned about both ground and air vibrations because the residents nearby are located less than 2 km to the southeast of the mine.
