Abstract: Based on a comprehensive analysis of the management methods, management responsibilities and rights, management con-tents and requirements of the special geological mineral investigation assessment project, this paper discusses the problem as to how to use workflow technology and rapid development platform to establish the special geological mineral investigation assessment project management system with pure B/S system architecture based on SOA which is aimed at tackling management abuses and current management problems of the traditional methods. The system has several functional modules, such as project information manage-ment, project initialization management, work plan approval management, contract management, commission business management, conference management, quality management, achievement management, archive management and statistical analysis. This system re-alizes full-service project management and on-line full life cycle procedure management. It can not only satisfy the work require-ments of staff members at various levels and improve the work efficiency, but also advance the normalization, systematization, infor-mation and science management level of the project management effectively. This system plays an advising and referencing role in the project management work of the relevant organizations.
