As to the previous random parameters were selected from- infinity to + infinity , which was far from the practical engineering. So based on the distribution of theories, the stress-strength interference model of cutting off-tail distribution at two ends was put forward. On the basis of the model, a formula of reliability was erected. And the reliability of mining engineering was studied when stress and strength obeyed the cutting off-tail distribution. An application case study of this method in a mining engineering in Hunan province, which concludes that the reliability of the cutting off- ta...
