Abstract
The procedure to estimate growth in load exerted on interchamber pillars with time is based on mathematical modeling of stresses and strains in structural elements of room-and-pillar mining method and on roof rock failure criteria. The calculation results illustrate a real time scale of variation in strength of rocks and the associated partial collapse of a parting and failure of edges of interchamber pillars when their height is increased.
