Mitigation of floor heave in West Kentucky Coal Mine
International Journal of Mining Science and Technology, 2016 A West Kentucky mine operation in No. 11 seam encountered floor heave, due to the localized increase in the thickness of the fireclay mine floor. Floor heave has overridden seals installed in two mined out panels. The third seal\u27s location was planned
