With the development of coal technologies, the previous management mode has been unable to meet the requirements of modern coal mine construction, so it is essential to design a new and effective security management information system. The design of this system is based on B / S structure, which main function is to collect and analysis the basic information of coal mine. In such a management information system, administrators can keep abreast of information in coal mine, detecting the abnormal situation timely and solving the problem effectively. Besides, the information input module in the system is easy to use, and users can also filter the information when using the system to inquiry, the query results can be outputted in tabular form. The system can also sort out all kinds of violation cases and accidents in the form of security information report, showing to the administrators. In another data analysis module of the system, it reveals the contents of the security information table by a bar chart. To ensure the security of the system, login steps are needed. Anyone who entering this system can modify the password, but each person’s permission is different, and they can only operate within their own permission scope.
