Abstract

Water-flowing Fractured Zone(WFZ)'s Height is an important research content of mining.Based on the features of rock failure,combining with analysis of deformability and bearing capacity,a mechanical model prediction WFZ's height was given in this paper.By which the influence of different strata combinations on WFZ's Height was analysed.Fracture evolution trending under different strata combinations was simulated by RFPA numerical analysis software,which consistented with conclusions of theoretical analysis.
- water-flowing fractured zone(WFZ),
- strata combinations,
- numerical simulation
