Backfilling is being increasingly used in underground mines for ground control and wastes disposal. The behavior of backfill is significantly influenced by its interaction with the surrounding rock mass and support structures such as barricades. Previous work conducted on backfilled stopes, including some recent studies by the authors, indicates that the theory of arching can be used to estimate the earth pressures in narrow, vertical backfilled openings. In this paper, a new 3D analytical… CONTINUE READING
