| Abstract: | The relation between the properties of overlaying strata and the propagation directions of the exploitation effect was studied. In is found that the softer the overlaying strata, the stronger is the influence on the maximum subsidence values at the earth's surface; and the greater the dip angle of a coal seam, the larger is the change of maximum subsidence values at earth's surface, when the pitching coal under buildings, water and railways is extracted. The conclusion has the important significance for forecasting the locations and maximum subsidence values, selecting correctly maximum subsidence angles, predicting the moving directions of the extracted roofs, preventing caving and keeping safe production in mines. |
