M.Sc. (Geology) / There was a possibility that the rockbursts experienced in the faulty Klerksdorp Goldfield area could be related to the numerous faults, fractures and dykes occurring in the area. Until the end of 1979 it was impossible to establish with any degree of certainty which discontinuity was associated with most of the seismic events, as the location network was too inaccurate at that stage to determine such associations. The accuracy of the network was subsequently improved to 30 m in all directions in a specific area of the macro-network. Twenty seven percent of the seismic events which located in this area, occurred less than 30 m from the faults, 21 percent were less than 30 m from the dykes, while 42 percent occurred less than 30 m from dykes and faults. The remainder ( 10 percent) were located more than 30 m from any of the abovementioned discontinuities.
