Evaluation of Coal Floor Water Inrush Risk with Five-Figure and Double-Coefficient Method

Abstract:

The coal seam floor water inrush risk assessment is the basis and foundation of inrush water disaster prevention^[1-, this paper uses five figure double coefficient method evaluating NO.16 coalseam floor water inrush risk of Xin'an Coal Mine. Contour figure of the destroyed floor protection layer depth, the floor protection layer thickness, the head above seam floor, the effective protection layer thickness, and evaluation figure of mining above aquifer which can guide coal production were drawn to given the security zone within mining area and ensure safe mining.
