Underground mining fault tree analysis and a computer aided analysis system for Jinchuan No.2 Mine

Jinchuan mine is the largest production base of nickel in China. The geological conditions in the mine field is very complex owing to the facts that faults and joints are very developing, buried depth of ore deposit is large and tectonic stress is high so mining conditions are extremely difficult. There are accidents in mining production. Considering mining and geological conditions in Jinchuan nickel mine, fault tree analysis was performed and a computer aided analysis system developed. The system contains 21 fault trees in 6 mining production systems, that is, driving, supporting, transport lifting, mining and filling systems. This paper briefly introduces the computer aided analysis system and its application.
