Abstract: In order to realize the distributed collection,processing,analysis and comprehensive analysis of production operation data under the control mode of mining group,OLAP is applied to design and develop the production operation and decision-making system for mining group.With the information technology,system framework is build which is consist of production and operation index system,parameter management,service components,data processing,data warehouse,OLAP and report tools.In the meantime,the function structure of system sub module is planned.The data storage structure of the system is organized by Database technology and the multidimensional data set oriented to the theme of production operation is built by OLAP,which is the prerequisite for the analysis and visualization of the multi-dimension data.In addition,the system has been constructed and applied in a Chinese mining group.And realize the distributed data extraction,data auditing,report generation and statistical analysis,which could effectively improve thelevel of production operation management and the ability of scientific decision-making.
