Underground mining carries several risks associated with blasting, which is essential for mineral extraction. Here are the five main risks:
Uncontrolled Explosions
Explosions can get out of control, causing structural damage and endangering personnel. Rigorous design and execution procedures for blasting, along with the use of advanced technology to monitor the precision of explosive charges.
Release of Toxic Gases
Blasting generates toxic gases such as carbon monoxide and nitrogen dioxide, which can be hazardous if not properly ventilated. Efficient ventilation systems and continuous monitoring of air quality.
Rockfalls
Blasting can cause instability in the walls and roof of tunnels, leading to rockfalls. Constant inspection of rock stability and the use of support techniques such as rock bolts and wire mesh.
Vibrations and Noise
Blasting-induced vibrations can affect the structural integrity of tunnels and nearby structures, as well as cause annoyance and damage to hearing. Monitoring vibrations and using controlled blasting techniques to keep them within safe limits.
Failure of Detonation Systems
Malfunctions in the detonation system can cause misfires or unintended detonations. Use of highly reliable detonation systems and continuous training of personnel in the safe handling of these systems.
It is crucial to follow strict protocols and conduct regular audits to minimize these risks.
