with different span and position has different influences on the slope stability. The stability of slope with different goafs was analysed. The results show that the safety factor reduces by 20% when the goaf... decreases. The safety factor of the slope is greatly influenced when the goaf lies in the bottom of the slope. The goaf may make the slip zone thicker when the goaf lies near the sliding surface......
