Hydration process of mixed systems with activated coal-gangue and cement;

Water dynamics of the 280 coal gangue dumps in Yangquan City, Shanxi Province was preliminarily studied by the analyses of physical properties, water infiltration characteristics, and water content of the weathered gangue.

In this paper, borrowing ideas from the research method of the spontaneous combustion mathematical model of goaf, applying to the hydrodynamic theory of porous medium, the spontaneous combustion mathematical model of coal gangue dump is set up.
