Abstract
The authors analyze gas control readings obtained in Butovskaya Mine, Kemerovo Region, in step-down phase of seismicity and after blasting operations. It is estimated how seismic waves induced by blasting influences methane drainage in coal seams. It is found that methane release from coal seam to roadways increases after seismic impact.
