Abstract:

Taking the semi-continuous process system of rock stripping as the research object, the article carries out statistical analysis on the failure time of process system equipment, adopts the mathematical software to calculate the reliability of main equipment, and obtains the whole system reliability for 0.696. The author points out the factors of affecting excavator and crusher, dumping machine reliability, and formulates the measures to improve the reliability of the whole system, which gradually makes the actual production capacity to reach the theoretical capacity to meet the normal production requirements.
