Pillar Strength . Pillar strength can be defined as the maximum resistance of a pillar to axial compression 9. In flat lying deposits, pillar compression is caused by the weight of the overlying rock mass. Empirical evidence suggests that pillar strength is related to both its volume and its shape 4, 6, 9. Numerous equations have been

Hence, if it is added to the concrete mix, the minute pore spaces can be reduced, resulting in high-strength concrete. Silica fume is also a pozzolana which will contribute to the strength. Thus, silica fume, along with superplasticizers is a necessary component of high-performance and high-strength concrete. 24. Polymer Concrete.

The gold deposits are hosted in very strong granodiorite rock that has a compressive strength of 300 MPa or five times stronger than commercial grade concrete. This makes for good mechanised mining conditions. The gold deposits today are accessed by two Declines downward sloping tunnels. Mining method is modern drill and blast technique.

concrete plugs in South Africa have been based on successful precedent practice, dating in particular from technical papers by Garrett and Campbell Pitt 1958 and 1961. Essen-tially, the length of the plug is determined by assuming that the rock-concrete plug contact area resists punching by a uniformly distributed safe shear strength.

Apr 13, 2019018332For rocks with a strength of 150 MPa, which is an average value for rocks found in gold mining regions in Southern Africa, this would equate to 60 MPa and correspond to a depth of about 2000 m, Wagner and Salamon 1975. In the case of the coal mines, the strength values range from about 30 MPa for coal and weak shale to 80 MPa for sandstone.
