| Abstract: | The theoretical calculation of first weighting interval of main roof and the utilization of measured data of roof weighting interval in practice for improving the accuracy of its calculation are both important to ground pressure control. Based on limit analysis of the plate construction of the main roof this paper derived a general formula for calculating the first weighting interval. And by utilizing the measured data of roof weighting interval, an inverse calculation method was put forward for determining and correcting the formulas' parameter to improve the calculation accuracy. |
