Conceptual diagram showing subsidence processes shortly after longwall mining <br /> (dynamic state). Enlargement shows some possible water flow directions in the fractured zone <br /> along fractures and separated bedding planes within the fractured zone. Enlargement 2 shows <br /> deflections of material in the near-surface and continuous-deformation zones and resulting tilt, <br /> curvature, and strain. <br />
