Abstract: In this paper, a full-level self-management information assessment platform based on safety integrity is studied, aiming at improving the efficiency and transparency of coal mine safety management. Research through the construction of big data operation platform, to achieve cadre self-discipline, employee consciousness, team autonomy, district team autonomy, professional self-control of the whole level of safety management process information. The Java development language, HTML5 technology and the Eclipse integrated development environment ensure that the system is easy to operate and intelligent. The results show that the platform realizes automatic statistical analysis, accurate evaluation, dynamic early warning and other functions, effectively improves the safety management level, reduces the difference of manual evaluation, and ensures the fairness of the results. At the same time, by updating the basic data in real time, it provides an accurate basis for decision-making and promotes the construction of smart mines.
