Fatal gas accident prevention in coal mine: a perspective from management feedback complexity

In order to reduce fatal gas accidents in coal mines in China so as to lessen miner injuries and economic losses, this paper describes a system analysis of fatal gas accidents in coal mines. From management complexity to system dynamic perspective, causes of fatal gas accident are discussed and the approaches to prevent accident are studied. Time delay and feedback effect of organization safety commitment in the system are simulated. The research shows that the time delay and feedback bring up complexity in the coal mine system. With causing mechanism analysis in the process of incident, the authors provides kinds of suggestions for coal mine administrator in decision-making from system dynamics perspective to preventing the fatal accidents, which is helpful in reducing fatal gas accident of mining industry in China.
