Distributional characteristics of vertical stressesThe distributions of vertical stresses are also influenced by stress isolines are staggered by the fault stress is focused on the rock seam round the two ends of the fault. In model I,the stress is concentrated at the lower part of the orebody on the lower fault the depth increases
