Numerical Simulation of the Effect of Stress on the Seepage of Fractured Rock Mass

Figure 15

The plastic zone distribution when the working face length is 200 m, 220 m, 240 m, and pushed to 250 m.

(a) Working face length is 200 m and advances to 250 m

(b) Working face length is 220 m to 250 m

(c) Working face length is 240 m advancing to 250 m
