Analyzing the reliability of system needs plentiful data by means of system faults statistic. Based on the viewpoint that shift output of fully-mechanized face is the result of various random factors’ synthetical influence, the process of how to analyze its reliability was deduced by using probability theory, symbolic statistics theory and systematic reliability theory combined with the concrete case study in this paper. And it has been proved that this method is feasible and valuable.展开更多

Taking the maximum of system’s total throughput as a objective, the method of determining the surge bunker’s rational size is put forward. Also, the problems of rational position of surge bunker are analysesed.展开更多

The uncertainties of the physical and mechanical properties of geotectonic mass, the surrounding rock stability, the nature condition, the equipment operation, the personnel and the external environment are proposed and described. The stochastic analysis should be widely used for considering the impacts of the uncertainty on the mining engineering. The economical risk analysis and the stochastic index system should also be set up in the mining engineering.展开更多
