Abstract

An investigation was carried out to evaluate the level of ground vibrations induced in a blasting operation at the Felele Quarry Company located in Lokoja, Kogi State, Nigeria. The equipment that was used in measuring readings was the Vibro monitor for some weeks. A digital camera was used to take snapshots of the blast site during the blasting operations and the effects of the blast on the residential buildings within the village vicinity. The results gotten show that all the readings fall within the allowable limits set by the Federal Environmental Protection Agency (FEPA). Moreover, the photographs of the buildings close by revealed cracks in the building walls. Recommendations were made pertaining to the procedure to improve the present blasting operations Keywords: Quarry, Felele, Blasting, Ground vibration.
