Predicting Overburden-Induced Failure Height of Large Mining Face in Shallow Coal Seam Based on Half-Plane Theory

<div>Contours of overburden stress increment. (a) Contour plot of vertical stress increment ratio. (b) Contour map of horizontal stress increment ratio. (c) Shear stress increment ratio cloud graph. (The abscissa is the dip direction of the working face, the ordinate is the height, and −60 m is the position of the working face).</div>
