ABSTRACT

Gole-Gohar iron ore has located in IRAN. Reduction of costs at this mine is too
effective for mining benefits. One of the important parameter about these costs is the pit
slope support with control blasting operations. In this project, we try to use the buffer
blasting method for suitable pit walls. Buffer blasting is a method that uses the faults for
smoothness of pit walls. In this method, we do not use the control holes. So, by using
the buffer holes, the control blasting operation will be suitable. Besides, the amount of
blasting agent, spacing and burden has designed for Gole-Gohar iron ore. After three
tests about buffer blasting, we obtained good results about north walls.
