In the mining world, for a num- ber of reasons, the size of mining operations con- sidering an OP-UG transition is strongly increasing. (Table 1). In the decision-making process, various factors should be taken under consideration. One of them is an assessment of the impact of underground mining on the stability of pit slopes.
