Abstract

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 of control blasting is too essential and also important. In this research, the effects of discontinuity’s condition has been investigated on the control basting results. This study showed that assessment of the above mentioned conditions can help to anticipate and prevent the happening undesirable disasters before performing any control blasting.
