Examining mining accidents from the angle of system analysis, we will find many basic problems, such as chaotic ordinate market, regulation failure, too weak or too strong government and so on. We could not attribute mining accidents only to the moral shortages of government officials and mining employers, or simplify the problem as profit seeking; management system is the basic point. We should not only rely on the inner management and technology prevention of the enterprise, but also fix our sight to the comprehensive model of society - technology. Considering social non - technological factors, public management is the key point of reconstruction the mining systems.
