The optimization of stope layout is defined as looking for a boundary with the highest profit considering
technological and geometrical constraints. The first algorithms were presented about five decades ago for
optimization of mining limits. Most of algorithms, presented till now, have been applied for optimization
of open pit limits. Few algorithms have been presented for underground cases, most of which have
been tailored for a specific mining method or use heuristic techniques. These heuristic algorithms do
not guarantee the true optimum. There are, however; some rigorous algorithms, which provide true
optimum, but they fail to provide 3D solution. In this paper, a new algorithm is introduced to optimize
stope layout, using integer programming technique. The algorithm is implemented on a specific model,
derived from conventional block model. It is a rigorous algorithm and provides a realistic optimum
solution, compared to its alternatives. For the first time, two more constraints, namely the minimum
width of rib pillars and the maximum stope height, are considered in the proposed algorithm.
