Abstract

Open pit mines have very high economic and operational risk because of high rate of production and using large scale machines. So, it is necessary to guarantee the availability of the operational equipment. First stage of mining in these mines is drilling for blasting and the availability of related machines has direct effect on all subsequent operations and consequently on overall economy of the operation. Today, operation conditions and machines availability can be assessed and analyzed due to development of RELIABILITY methods in different engineering fields. Markov method is one of the potent methods in this context which is based on STOCHASTIC PROCESS theory. In this study, RELIABILITY of ROTARY DRILLING MACHINEs in Golgohar Mine No.1, Sirjan, is analyzed using this method. In this way, RELIABILITY is calculated by investigating failure dad of these machines during 5 years and modeling different conditions of their availability. So, at least 2 machines will be ready and available for drilling operation with the probability of 95.42% corresponding to 347 days out of total 363 working days.
