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, th...

One of the most important factors that can have notable effects on costs of stripping, drilling and blasting, loading and haulage due to disasters in mines is supporting the final pit slope by control blasting. Condition of existent discontinuities in rock mass toward the pit benches has a special influence on results of control blasting. In fact, factors such as dip, orientation, spacing, filling, etc. extremely change the outcomes of control blasting. Therefore investigation of discontinuities effects on results...
