Stone quarrying is basically a labor oriented small scale industry which involves blasting, drilling and crushing activities. Due to unscientific and unplanned blasting activities the resulting environmental damage has become a growing concern to people in general and environmentalists in particular. With the introduction of sophisticated machinery in to the quarrying operations, the noise problem which was never co, sidered to be serious in the past also needs the immediate attention of environmental managers. It has been established that noise interferes with speech communication and causes annoyance and distraction. With the increase in the scale of quarrying operations heavy blasting has to be restored which is resulting in ground vibrations causing damage to the structures in the vicinity besides causing irritation to the people residing near by. These operations create problems to both the community associated in the extraction of minerals and the local inhabitants by virtue of imbalance in environment like sound, vibration, fly rock and air blasts. This paper highlights various environmental problems associated with blasting operations and the methods to be adopted for mitigating the same.
