WebGenerally, damage from seismicity is driven by induced stresses from mining activity, geological structure and weakness of the rockmass [2]. Methods to prevent and mitigate … WebSeismicity mainly concentrates on the longwall panel S109 where mining operations are conducted and the adjacent broad area north of it, which is known as a tectoni- cally prestressed region characterized by dipping of the coal seam and by tectonic faults. WebThere are several seismic phases, but only S-waves and P-waves are commonly recorded in mining induced seismicity. P-waves, or compressive waves, are the first ones which arrive at receivers. When seismic waves propagate, they carry energy from the source of the shaking outward in all directions. trimax home gym
