Abstract Minin-induced water inrush from a confined aquifer due to subsided floor karst collapse column (SKCC) is a type of serious disaster in the
underground coal extraction. Karst collapse column (KCC) developed in a
confined aquifer occurs widely throughout northern China. A water inrush
disaster from SKCC occurred in Taoyuan coal mine on February 3, 2013. In
order to analyze the effect of the KCC influence zone’s (KCCIZ) width and
the entry driving distance of the water inrush through the fractured channels
of the SKCC, the stress, seepage, and impact dynamics coupling equations
were used to model the seepage rule, and… More >
