The computer Simulation of Loose Materials Displacement and Its Practical Application in Mining

摘要

On the basis of analyzing the results derived from Jolley's model, a new computer simulation criterion is put forward by displacement field similarity. A probability equation of loose materials displacement is proposed through experiments of loose materials drawing and is used as the simulation mathematical model. It has been proven by practice in three mines that the new simulation process can satisfy the requirement of optimization of structure parameter of caving method in underground mine when loose materials constituted by broken ore is less than 60-meter high.
