| Abstract: | A probabilistic model on calculating the height of mining-induced overburden fractured zone is deduced by using reliability theory,as the variability of indices is taken into consideration in this paper.An example preliminarily shows that the model is practical.The model,in turn,is used for the prediction of heights of mining-induced overburden failure in Jinxiang coalfield. |
