The process of mining one way or the other affects the environment. These effects can ultimately lead to damage to the buildings which may include tilting, disruption of utility lines and foundation cracking. The land subsidence which is caused because of the underground mining is most likely to cause damage to the buildings. After the coal is extracted, the mine is left to collapse, which causes the land above to sink which will damage the buildings near and on it.
Hence, the correct answer is 'land subsidence'.
