Abstract: Intelligent decision support technology architecture for wisdom mine based on new generation of big data technology and cloud computing technology was put forward based on analysis of application status of mine decision support system. The architecture uses Hadoop and other big data technologies to solve problems of traditional decision support system, including unable to horizontally expand computing resources, long response time, and unable to analyze data combining with discrete management information data and automated measurement and control data; through introduction of stream calculation, sovles problem that the traditional decision support systems can not effectively deal with unbounded data. The architecture has capability of carrying out professional analysis model of mine and information business analysis model for general management, it can fully integrate relevant data of"people", "machine", "ring" and "management", form a comprehensive decision support information, and provide core technical support for realization of mine intelligence.
