Abstract
Based on field test results of three underlying influential regions below coal seam floor in Xinzhi coal mine,the failure depth,water resistance and space-time characteristics of coal seam floor failure were analyzed.A minimum critical water inrush coefficient which can provide a practical evaluation basis was established to evaluate the mining condition under water pressure.This research result can be referential for other coal mines.
