Optimization of parameters for isolation pillars in a certain iron mine converted from open-pit to underground mining
Mineral resources extends from shallow to deep,open-pit mining is often used in the upper part.However,with the gradual depletion of shallow resources,the shift from deep to underground mining has become an inevitable trend.In the process of converting open-pit to underground mining,there are some challenges,one of which is how to optimize the design of isolation pillars to ensure the safety of upper and lower mining,the continuity between open-pit and underground mining,and the maximum improvement of resource recovery rate.This article aims to study the optimization methods and techniques for isolation pillars in open-pit to underground mining,providing reference for the safe and stable implementation of open-pit to underground mining in similar mines.
