Effects Of Mining on the Environment and Human Health

Underground mining causes huge amounts of waste earth and rock to be brought to the surface - waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. This causes serious damage to buildings.

Seismicity Induced by Mining: Recent Research - ScienceDirect

Seismicity induced by mining is commonly described as the occurrence of earthquakes caused by rock failures, a result of stress changes in the rock mass near mining excavations. Mining-induced events are caused by increases in the shear stress or decreases in the normal stress acting on the fault planes.

Mining-Induced Seismicity in the Saarland, Germany - DeepDyve

The shear events cannot be explained by the mining process alone. They are presumably induced in certain regions (bands) under tectonic load by an interaction of mining-induced and tectonic stresses. In February 2008, extraction in the Primsmulde field induced a seismic event of magnitude 4, which led to surface vibrations reaching 93 mm/s.
