Abstract:

Mechanism and phenomenon of subsidence induced by mining under fragmentized rockstrip was analyzed in the paper.Discrete elementmethod, DEC and control param eters of the UDEC were introduced. The mechanism was testified with discrete element numerical simulation through an engineering example.

Key words: discrete element, numerical simulation, fragmen tized rock-strip, subsidence
