| Abstract: | Based on results of the statistical analysis of a large amount of measured data in mining engineering,the theoretical model for analysis of ground subsidence due to deep sub-critical mining of iron ore-deposit is established by using the theory of stochastic medium.The formulas of two-dimensional and three-dimensional problems are developed and applied to the prediction of the ground subsidence due to deep sub-critical mining by pillarless sublevel caving method.The agreement of the theoretical results with... |
