| Abstract: | According to the specific conditions of roof-coal being mined in thick seam sublevel caving mining, a computer simulation method for studying the roof-coal displacement has been proposed in this paper based on the discrete theory of cohesionless particle stochastic flow under gravity. A systematic exposition of simulating fundamentals, function and the way one put into effect have been made in the paper, and two application cases have been cited which proved that the computer simulation method can be used to investigate the entire process of roof-coal drawing and forecast the recovery of roof-coal under mine productions. |
