Abstract
Based on the importance of the floor grouting reinforcement techniques in the prevention of floor pressurized water inrush accidentsin China's water haz
ard mine area, the paper summarized the developmentin theoretical methods and engineering practice, including the floor grouting techniques of the calculation method
for the failure depth of coal seam floor in deep mine, the structural mechanics model 'porous and fractured lift type'of water inrush in coal faces, the simulating test for g
routing reinforcement, the DC detecting method for the failure depth of coal seam floor and the reinforcement parameters in Zhaogu No. 2 Mine. In the end, the outlook
of water- inrush mechanism, grouting materials research, development of detection and water control methods progress were proposed.
