Abstract: Based on the discussion on the mining failure law of overlying strata above the mining face and theoretical analysis of
mining damage height, this paper proposed several methods that can effectively measure water diversion height in practice
combined with occurrence condition of 3^# coal seam in Qinshui Basin, then analyzed and evaluated discharge effect by discharging
affective water-bearing layer.

Key words: water flowing fractured zone; fractured zone; maximum water conducted fissure height; curve subsidence zone
