HEREDITARY PROBLEMS IN LONG-WALL MINING BY FREE HEXAGONS
Original language description
In deep mines, the way of excavation, depositing packs, and the mechanical properties as well as the velocity of mining belong to the most decisive phenomena for the threat of bumps. In this paper, time-dependent hereditary creep problem in terms of freehexagon distinct element method (DEM) is formulated and solved for assessment of bumps occurrence in deep mines. The time factor as an impact of the velocity of mining is involved here in a natural way in the model of discrete elements. Inside of theseelements, the material behavior is described by the boundary element method. Mutual coupling of the velocity and the way of deposition of packs can principally influence the safety against bumps.
