Abstract
As Shanxi Province is rich in coal resources, the output of raw coal approximately
accounts for one quarter of China's production. It is one of the most important energy and
heavy chemical bases and plays a significant role in the sustainable development of the
national economy and energy security. With the continuing exploitation of coal resources
in Shanxi, water environmental problems such as the destruction of water resources and
deterioration of water quality have become increasingly prominent. Especially with the
closure of many depleted coal mines, water pollution caused by acid mine drainage (AMD)
has become more and more serious, which aggravated the shortage of water resources and
threatens the safety of local drinking water supply. Since 2008, more than 100 coal mines
have been abandoned in the Yangquan coalfield of Shanxi, and the AMD has polluted the
surface water and groundwater in the Niangziguan spring catchment.
