| Abstract: | The effective extraction thickness with in the distance between the edge of opening and the point of inflection is regarded as a power function in the paper From the point of this view,the paper has presented the predicting method of surface subsidence for improving the predicting precision. According to the Systematic analysis on the measured data, the author concludes that the shape factor or the power exponential is of diect proportion to the ratio of the distance between the point of infleCtion and the edge of opening to the influence radius. |
