Description : Our study was carried out to assess the level of noise generated and ground vibrations induced during blasting operations at the Ewekoro limestone quarry in Nigeria. To achieve this objective, vibro monitor equipment was used to take readings related to noise generated and ground vibrations during all blasting operations that took place in the quarry for a period of one month. As well, a digital camera was used to take photographs of residential structures within villages near the quarry. The results obtained indicate that the ground vibration readings fall between 0.5 mm/s and 2.1 mm/s and the noise generated during the blasting operations between 82 dB and 89 dB. These readings when compared with the limits set by FEPA (Federal Environmental Protection Agency) of 5.0 mm/s and 150 dB) all fall within the permissible limits. However the photographs of most structures near the quarry reveal cracks and dilapidated building walls. Recommendations are made on how to sustain and improve current blasting techniques.
