Abstract: Based on the security system engineering, the fault tree analysis method with the reliability theory is applied as a system analysis tool to create a fault tree which can clearly reflect the relevant factors in the foam dust removal system and their cause-results logical relationship. In combination with foam capture model and the related experimental results, various proposals on the foam dust control system are analyzed. Finally, it is proved that the probability of events occurrence and the importance order of each bottom event can be obtained from the foam dust removal system. By building a proper mathematical model, the mechanisms of coal dust control system is analyzed and evaluated.
