Abstract: The paper analyzed and summarized the mine informationalization and intelligent features and provided mine informationalized and intelligent three layer application architecture, including monitoring, control, surveillance and communication layer, production and safety management layer, operation management and de cision support layer. A general requirement of mine informatinalization and intelligence was provided and an integrated design should be designed according to the pri nciple of safety reliable, advance in application, easy maintenance, expansible, general design and step by step implementation. The information transmission platform, interface specification, data coding, database, information processing platform and others should be unified. The key technologies and requirements of mine information alization and intelligence were provided, for example, a mine monitoring and control network should be interconnected with the office network and internet via a net gap and other network security equipments. The cable of a mine wire dispatching communication system should be special. The mine monitoring and control system and the visual sureillance system should be strictly forbidden to be concentric.The mine safety monitoring and contral system and the wire dispatching communication system should have two main optical fiber cables and two cables individually and those cables should be sent to the underground mine through different mine shaft or a same mine shaft in different locations with a certain interval. An image surveillance system should have an intelligent discernment function.
