Trends and causes of fatalities in South African mines

As shown by the breakdown of the gold mine fall of ground under- ground fatality rate in Fig. 7, the rockburst rate has risen since 1960. Presently it is probably the highest in the world. There were 95 deaths due to rockbursts in 1988 alone. The rockfall fatality rose until the early 1960s. Since then the rockfall rate has declined steadily.
