...- fined. At M2, the main vein lies at (Mine Grid 60/100) and 11 sub-parallel faults (ranging from Mine Grid 90/125 to 90/145) and 10 main joints sets have been defined. The measured stresses are re- solved onto these faults and joint sets later to indi- cate the shear stress conditions currently accommo...

... crack did not appear in the block for which the expansive steel pipe rock bolt was set in, even if the displacement of the block ex- ceeded 10mm. If it is assumed that the shear force was all sup- ported by the cross section of the rock bolt, we can calculate the shear stress on the rock bolt by divid...

... studied in the min- ing environment. However, it is applied from a dif- ferent perspective, viz. to assess the impact of min- ing spans and mining rate on structures. As such it is used routinely and is referred to as Excess Shear Stress in the South-African underground mining en- vironment. This paper...

... apertures at several kilometers depth. Deep-well measurements demonstrate that fractures that are under differential shear stress are more likely to be water conducting, and those that are principally under normal stress are less likely to be water conducting. In this paper, alternative interpretations...

.... Nevertheless, it was found that very little shear stress was induced on the abutments as a result of integrating the micro seismicity. It is estimated that the measured differences in shear stress would be about 2.5 MPa. Several areas on the undercut level were selected in order to find a relationship...
