Alluvial soil plays an important role in ground subsidence caused by coal mining and groundwater extraction. Field-measured data show that when a coal mining area is covered with thick alluvial soil, mining subsidence in these areas shows some unique phenomena (Zhou 2014; Zhou et al. 2015, 2016a).For example, the subsidence factor is greater than 1.0 (the maximum subsidence is greater than the ...
