New Model of Burden Thickness Estimation for Blasting of Open Pit Mines

Suitable pattern design of drilling and blasting is very important in open pit mines. Using explosive energy for rock fragmentation with minimum cost production one the purposes The most parameters are including diameter hole, specific charge, burden thickness suitable dimensions fragmentation. In this paper, charge calculated based on quality mass then definition maximum mines calculated. a new models estimation quadratic equations presented. Therefore, equations, other corrected. Also, validation results article show thicknesses have slightly differences experimental results. error equal 3% obtained data. output these can be reliable accurate calculations thickness.
