Abstract: The paper analyzed existed problems of current management system of hidden danger of coal mine and proposed a solution of quantization management informatization of hidden danger of coal mine. The scheme integrates closure processing, hidden danger analysis, connection between hidden danger and accident together organically, and uses hidden danger collector to complete closure management process of hidden danger of coal mine. The actual application showed that the scheme shortens processing time of hidden danger and improves processing quality of hidden danger, which reduces incidence of various accidents effectively.
