According to the results of monitoring with a temporary network of seismological stations in the south of Kuzbass in the area of seismic activation of technogenic nature, formed under the simultaneous influence of open and underground coal mining, the spatial structure of activation, its development in time and connection with tectonic disturbances are studied in detail. Seismic activation near underground workings is distinguished by locality in area, a large number of earthquakes with magnitudes Ml ≤ 2. For three closely spaced coal mines, there is a general seismic activation, inside of which, as a local zone, there is the activation of underground workings, characterized by the strongest earthquakes with Ml in the range of 3 ÷ 4. Depths of foci have a two-modal distribution with maxima in the range of 1 ÷ 1,5 km and in the range of 2 ÷ 3 km. Both in the area of mines and in the area of open mine workings, the subsoil is significantly deeper than the mine workings seismically activated. The seismic process in time is not stationary and pulsating.
