Mechanisms of mining induced inrush of pressurized water in the floor containing faults

Vol. 62 nr 3

573--585

Investigating the propagation of the seepage path of confined water in the floor is an impor- tant means to determine the conditions of water inrush from the mine floor for deep mines with high water pressure. In order to better understand the mechanisms of water inrush due to the hidden fault floor above a confined water body, an integrated study including analyt- ical analysis, and similarity simulation experiments were conducted. The study focuses on the distribution of mining induced stress in the floor, the propagation of hidden faults, and the evolution process of water inrush channels during longwall coal seam extraction.
