For occurrence of confined water in floor limestone of 6 Coal Seam in Hengyuan Mine, this paper put forward applying additional geological exploration, optimization design for mining section and mining face, face exploration and test, local reinforcement with grunting into floor, pressure-relief by dewatering, changing floor aquifer by grunting from surface station to forming a set of water prevention methods including exploration, prediction, underground geophysical prospecting, evaluation, measure, inspection, monitoring and prevention. The application of these methods has eliminated effectively floor flood.
