Abstract: In order to solve the problem that it is very difficult to highly integrate geographic information and rescue resource together and use them deeply in the process of emergency rescue in large mining area. We use standard service and data interface to aggregate surface-underground map service, the mining area panorama and emergency rescue resource data to form "one-map" to solve the problem. The results show that the system can make full use of decentralized data and services to provide all-round rescue command and dynamic decision-making support by updating and sharing the data and services easily and being with a strong practicability.
