Reliability Analysis of Fully Mechanized Working Face Based on Appraisal and Distribution Method

Advanced Materials Research, 2015
Through the system reliability theory, the reliability of each subsystem of fully mechanized working face was got. The reliability of the working face was 0.82. By using the reliability of redistribution, the reliability of weak links of the system was improved to 0.966, so that the reliability of the working face was raised to 0.86. The reliability of
