Process Observation and System Reliability Analysis of Anjialing Fully-mechanized Caving Face

Through a period of nearly a month of process observation at B901 fully mechanized caving face in Anjialing coal mine,the paper analyzes the reliability of recovery system with reliability theory.The paper puts forward the needed observation links of fully-mechanized caving face from the specific content,and proposes how to analyze the system’s reliability of fully-mechanized caving face systematically,which increases the man-hour utilization rate of man-machine reduces the equipment failure in the working face.
