Abstract
Our country development pace has reached a stage whereby the quarry operators must improve it operational efficiency in the excavation of rocks due to constraint posed by the environmental requirement and the authority. The most important activities in the excavation operation in quarrying are drilling and blasting where the environmental impacts posed are ground vibration, noise, fly rock, dust and gases. So this project would emphasis the effect of ground vibration and noise on the environment pertaining by granite quarry operators. The objectives of this project are to observe the usage and handling explosive at the quarry and to determine the related field coefficients for the calculation of ground vibration which result from blasting activities. Data from the quarry operator and the vibration level are measured by using blastmate and blastronic. The ground vibration is low where the site constant of β=1.5323 and k=525.9. The average observed noise level of 110.93 dBL is also low comparing to the standard level determined by the authorities. Even though the operating quarry followed all the laws and regulations required but still chances of environmental impacts are there. As there is no way to prevent it so the best way is to control and minimize the level of the environmental impacts. These can be done perfectly with the cooperation of all the parties that involved.
