Rockmechanics models have been established for different types of rock structure to offer a reliable mechanical basis for the analog analysis of host rock stability while mining in a broad area.
In this paper based on principles of rockmechanics the roles of safety pillars in mining is evaluated. Some recommendations for their safe mining are provided.
