Distribution of seisms foci during the mining of 19th eastern longwall and Eastern inclined longwall #3

摘要

The paper presents the results performed at the O.F. Zasiadko mine seismological observations on the registration and location of seisms that occur during the mining of the m_(3)bed. According to the constructed magnitude-frequency relationship for the worked out longwalls, it was concluded that the longwalls worked out in different mining-geological conditions differ in the relative energy of seisms, in their number, recording time and spatial location of foci.
