The ground motions recorded in the earthquakes are time-domain signals, which do not convey information on the frequency content. Similarly, the amplitude-frequency representation obtain

Water Hazards in Coal Mines and Their Classifications,o underground workings or open pit mines when tunneling or mining exposes water-bearing media, such as high-pressure confined aquifers, surface water bodies, or underground mine pools. Mine water inrush generally occurs dramatically and can flood underground workings in a short period of time, jeopa
