| Abstract: | The paper puts forward the idea that the rock is showed as the mechanics model of Maxwell style and elastic element series and consider the root on the top of coal layers and the winning district after under ground mining as visco-elastic contileuer feam on the basis of visco-elesticity. According to the theory cf the bend of contilever feam, the puper has deduceed the ground subsiding calculation folmular of the upper palts of the winning district diitrict and cool layers. |
