Abstract
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.
