Evaluation system of water inrush in coalmine based on J2EE

摘要

Water inrush is in the second place among the mine disasters in coal mine. In order to informationize impact factors of water inrush and evaluate risk of water inrush, we put forward a evaluation system of water inrush in coal mine based on J2EE. The J2EE, data warehouse, Online Analytical Processing (OLAP) and data mining technologies are used to build a multi-tier water inrush system based on J2EE. A new architecture for the DSS is proposed to describe the new application model. A method is presented to collect data from traditional operational database and to store the data to data warehouse and data mart. And Bayesian network model, single source model, multi-source model are realized to provide water inrush officers with efficient decision support.
