ABSTRACT

The environmental problems arisen from ground vibration and air blast have
been faced and discussed frequently in various industries such as mining,
construction, quarry etc. where blasting operations are unavoidable. So the ground
vibration effects induced by blasting on structures and human beings need to be
predicted, monitored, and controlled. With the increase of the environmental
constraints on the levels of disturbance induced by blasting operations nearby
residents, there is also an increasing necessity to design cautious blasting with
greater precision. Therefore, the determination of maximum amount of explosive
per delay for a certain distance, especially in large blasts, has a great importance
for the elimination of these environmental problems.
This paper presents evaluation of the damage risk of the ground vibration
induced by blasting, which was performed at The Naipli Quarry that supplies a
cement plant in western of Turkey due to increasing complaints of the
neighbouring villages. Therefore it had been necessary to control the blasting and
to predict the level of vibration in order to prevent the damage to the buildings
located nearby this site and to reduce these complaints.
Within the scope of the study, ground vibration components were measured
for 20 events using 5 different types vibration monitors (3 White Mini-Seis, 1
Instantel Blastmate and 1 Instantel Minimate Plus Model) considering the
directions of the villages, in order to predict the peak particle velocity, determine the slope of the attenuation curve together with the maximum charge per delay,
and for the evaluation of the damage risk.
