Abstract:  Due to low efficiency in intelligent informationization of metal mines and serious information blockage in the production process， the implementation of manufacturing system is conducive to the information circulation， which is of great significance to the construction process of intelligent mines. According to the investigation and research of several mining enterprises， the key position of MES system is expounded. A framework model of modern integrated manufacturing system for metal mines based on three-tier architecture of ERP/MES/PCS is proposed. The key technologies of integration of MES system with ERP and PCS are discussed. Meanwhile， the functional module framework of MES system for mines is proposed and the selection of J2EE and. net development platforms and their respective development frameworks are analyzed and summarized to establish the E-R model and then design the relational database model. By this way ， the top-level design of MES system functional framework for mining-type selection in metal mines can be realized， thus providing theoretical basis for the construction of MES system.
