| Abstract: | According to the key strata theory to judge the key strata and the failure and broken law,the paper studied the relationship between the starting distance of the surface subsidence and the initial broken distance of the key strata.The paper has a comparison on the timing and difference between the actual measured starting distance and the primary broken distance calculated value of the key strata.The paper analyzed the difference causes and determined the scientific method for the theoretical calculation of... |
