The invention relates to a quantitative evaluation method for coal-bed top-plate water burst (inrush) conditions in coalfield and coal industry, which comprises the following steps: on the basis of systematic and comprehensive analysis on the geohydrologic conditions of a mine, finding direct and indirect water bearing layers closely related to the coal-bed top-plate water inrush, drawing a watery area chart and an inbreak safety area chart, and drawing a water burst (inrush) condition comprehensive area chart by combining all geoscience information of the two areas; and dynamically predicting the pre-exploration pre-evacuation proposal of the project water burst quantity and the top-plate direct bearing layer of the stope by using Visual Modflow professional software. From the quantitative and comprehensive analysis on the water burst (inrush) conditions to the quantitative simulated prediction on the water burst (inrush) quantity and the pre-exploration pre-evacuation quantity, the three-chart two-prediction method forms a whole set of systematic research train of thought and research methods, and has certain advantages in the whole and sectional project water burst quantities of the stope having higher requirements on prediction precision.
