Abstract

In order to obtain the influence law of mining depth on floor coupled stress-seepage characteristics, the coupled stress-seepage characteristics were studied by numerical simululation. The results showed that when the mining depth increases, the floor failure range progressively increase with expansion of confined water guide rise. As the guilde rise of confined water, the permeation velocity became slower. Finally, through the comparative analysis of floor failure process at 800m and 1000m mining depths, the reasonable width of fault waterproof pillar was determined. it was safe to reserve 30m and 40m fault waterproof pillar respectively at 800m and 1000m mining depth.
