| Abstract: | The problems of replacement lifetime of wire ropes used in mining are studied in this paper. Lifetime data are tested. Normal distribution and Logrithm distribution are tested by kolmogoroff test, Three parameters of weibull distribution are estimated by the method of least squares. The confidenee intervals of three parameters and reliability of wire rope in using process are given |
