For Manual management of mining drawings, cycle of designing and approval is difficult to control, and document management is a tedious task. Based on workflow technology for mining drawings, this paper analyzed business processes of mining drawings in the full life cycle, established a mining drawing dynamic management model and defined transfer processes of mining drawings. Four kinds of transition structures on workflow engine reflected connections and constraint relations among various activities during the transfer of mining drawings. Finally, this paper discussed the system's overall structure and the compositions of function modules, and described realization methods of the key technical details. The site application showed that the system realized the automation of process management in the full life cycle of mining drawings and improved the working efficiency.
