Prediction of the height of caving zone above the undercut in block

The block caving is one of the most commonly used methods in underground mining of massive low/high grades and deep deposits As a result of undercutting caving occurs and propagates toward the upper part of the ore block It is essential to predict the height of caved ore and its volume based on shape of the caved zone to make an economic decision
