Investigating Sustainable Blasting via Peak Particle Velocity Impact on Evbonogbon Town, Edo State, Nigeria

This research is hinged on the fact that blasting operation, a vital process in the extraction of solid minerals from mines and quarry, with its negative impact on the environment cannot be abandoned. However, with proper ethics and design parameters, the environment can be protected in adherence to the principle of sustainability. Slam stick X accelerometer was deployed to measure the level of vibration for quarry A, B, C and D, expressed as its Peak Particle Velocity (PPV), by comparing the result obtained for each of the quarry with the maximum acceptable threshold for PPV 50 mm/sec, stipulated by the International Organization for Standard (ISO). Sixteen (16) blasts were monitored for ISO compliance. The results from blast revealed that 37.50% of the blast initiated PPV that exceeded the maximum acceptable threshold of 50 mm/s recommended by ISO. This is likely responsible for the cracks in buildings and structural failure witness in the study areas while 62.50 % were below the recommended standard. From this research, houses within the quarries whose blasting operation produces PPV are lower than the 50 mm/s threshold lack visible cracks and the resident have positive perception towards the quarry operations. On the other hand, buildings close to quarry site generating PPV higher than the ISO threshold have several cracks and negative perception towards the presence of the quarry. The finding shows that site C experienced the worst blasting practices, while site B experienced the best blasting practices according to ISO threshold.
