The goal of mine enterprise information system is to improve the management standard and economic benefit. It provides service for data processing, different levels of subsidiary management and policy making in mine enterprise by using systemic science methods. This system can modulate and control mine production behaviors, guarantee the optimum efficiency of mine production through making full use of management information of production, judging the running situation of production, finding out the problems existing in the management, locating the reasons for maladjustment of mine production. The management information system of mine enterprise has close relationship with mining engineering, mine management and computer technology. This paper studies and solves the problems involving in the construction and application of mine-enterprise information system by not only combining computer network technology but also applying data warehouse technology and KDD to mine enterprise. The study can strengthen importance of information system in the management of mine production. In accordance with the collection and organization of the basic data needed by mine production, this paper propounds the idea that mine enterprise Intranet must be set up based upon the data. It also analyzes emphatically the structure and implement technology of mine enterprise Intranet, solves the problems involving in the seamless transference technology from computer application system and database to the mine-enterprise net, conserves to the utmost the investment in the former mine information management system. Practical application shows that mine-enterprise net is an effective structure of mine-enterprise information system, and can provide convenient, integrated and timely information service for mine production management. With the development of computer application, mine enterprise has collected a lot of data during the production such as mine geological exploration, extraction development engineering and mine management. But most of the data has never been used effectively because there is no ability in mine enterprise to store and manage these data synthetically. Based on this situation, the paper renders that the data warehouse should be set up in the mine-enterprise information system. The data warehouse should be one which has multi-dimensional structure based on the present application system database, and which through corresponding subject data, abstracts and transfers data synthetically, sets up data marts from the bottom to the top, then integrates the data marts into mine enterprise data warehouse by which solid data support for the management of mine enterprise is guaranteed easily. On the basis of data warehouse, the OLAP technology applied in this paper analyzes and processes the management data of mine production from different aspects in order to understand the situation of mine production. This paper analyzes the construction characteristics of OLAP and the multi-dimension characteristics of management data during mine producing, both of which are applied to practical mine production. The foundation of data warehouse provides strong data support for the intelligent diagnosis for mine enterprise. KDD technology can give more advantaged analysis to the management data of mine production existing in data warehouse and change the data into useful information and knowledge automatically and intelligently, which are effective way to realize the intelligent diagnosis for mine enterprise .By using KDD technology, the paper discusses the way to implement intelligent diagnosis for mine enterprise, propounds the structure of diagnosis system integrating data warehouse, OLAP, KDD , model database and expert system. These technologies, if applied to intelligent diagnosis for mine enterprise, are able to achieve effectively the uniform expression of data, diagnosis model and diagnosis knowledge. According to the undetermined characteristics of the diagnoses objective in mine enterprise, for the purpose of practical application, this paper studies the expression of diagnosis knowledge, in which the knowledge is represented by multidimensional and multi-arrangement methods and then integrated synthetically by many knowledge expressions such as fuzzy logic, neutral network, etc.. The intelligent diagnosis for mine enterprise can not only accumulate and reason diagnosis knowledge by using data warehouse, artificial neutral network technology and expert system integrating, but also simulate experts to find any factors to affect mine production through discovering knowledge models existing in the management production of mine enterprise form a great deal of data. Besides this, the paper applies evolution computation and natural inheritance law to analyze the management production data in mine enterprise and judge the production situation of mine enterprise .It indicates that evolution computation can either diagnose mine production activities directly or improve diagnosis efficiency greatly. The study result of this paper shows that the application of mine enterprise Intranet can construct a open, unified, convenient management window to manage information resource synthetically. The establishment of data warehouse lays the sound application foundation for developing the potential function of mine information system. Based upon the achievement, each kind of application such as analysis and process of mine enterprise data, intelligent diagnosis and decision support can improve management of mine production significantly and thus enhance mine economic benefit. The practical application of this system in mine enterprise shows that what has been achieved in this paper can be used for reference in the construction of mine information system and also has important application and popularization significance. |
