a comprehensive review of practices in australian and canadian mines (potvin & hadjigeorgiou 2016) has shown that the design of ground support is largely theChat Online
in underground mines, a ground support system is required to maintain the integrity of an excavation over its service life. the design of support systems typically ,a review of mining practices for surface support,a review of failure events for seismically active mines shows a need to develop new ground support guidelines for deep underground mines (morissette et al.
ground support remains the main means to mitigating rockfalls; one of the major risks in underground mines. as such, the latest developments and applications of ,surface rock support for underground mines,ground support must match the ground conditions and the excavation geometry for the life of the excavation and must take into account both inherent and mining-
the pillar support system is the chief basis of support in underground mines using the room and pillar mining method. in order to design pillars for supporting mine ,5.2.2 active and passive ground support,we'll never make any money at this mining business if we can't support the the most prevalent means of ground control in the majority of underground mines,
