摘要
///This paper collected the temporal and spatial distribution of 421 locatable events and studied focal mechanism solutions of the larger magnitude mine earthquakes, as well as the relationship between energy release and frequency statistics of hourly blasting. The result shows that the fault strike is consistent with regional tectonics. Associated with the increasing exploitation quantity of underground mining and the prior rare arid lasting about half year, the artificial blasting of larger magnitude affected the local stability of tectonic stress field which caused a series of rock-bursts.oft-com:office:office" />
