Abstract: Characteristics of coal mine digging linking and importance of management of the digging linking were analyzed, a kind of digital management system of digging linking based on WebGIS was designed, and structure, implementation and function of the system were introduced. The system integrates digging plan,linking of working face of production process and analysis and prediction of production volume together, and realizes organically integration of coal resources, farthest protects existed mine resources, and provides an integrated solution scheme to realize active control, running and optimal management of production plan and actual production of coal enterprises.
