| Excavating coal and grubbing are two important links in the process of coal mine production. The quality level of excavating-link in mining production plays a direct role in the safety and product-profit of the coal mine. And the emergence & development of Geography Information System (GIS) makes it possible to improve the efficiency of mining excavating-link, at the same time, the combination of GIS and mining fieldworks will serve coal mine enterprises better and improve the safety & efficiency standard of coal mine production.The paper comes up with a coal mine excavating-link management system based on WebGIS by introducing the B/S framework and using SuperMap IS.NET component technology. The system testing and running results indicate that the system is able to satisfy the requirements of coal mine production and excavating-link management. In addition, the system can be used simply, maintained easily, extended easily and managed conveniently. What's more, it provides the better early warning mechanism for the excavating-link planning and real-time work schedule, which paves the way for the coal mine management modernization, network and information.The paper introduces the research background, the system developing circumstance and the relative technologies. And then, it designs the system framework and every function model in details. It illustrates some main models, including Single Sign-On (SSO) power model, map online edit model and excavating analysis model, etc. Besides, the paper designs WebGIS data transporting safety platform based on the agent middleware technology according to the situation to which the system will be applied. In the end, it provides the testing flow chart by which the system has been effectively tested to make sure that it runs safely.At last, all the work is summarized and some research prospects of the subject in future are promised. |
