Abstract:Based on previous study,the intrinsic relationship between the developing of waterconducting fissure zone(W-F Zone) and the stress variation in surrounding rocks of the roof has been analysed by means of numerical simulation.It had been proved that the developing of W-F Zone was dominated by tensile stress,and the numerical simulation could be used to predict the developing of W-F Zone.

 

Key words: backfilling method; numerical simulation; stress state; water-condlucting fissure zone
