Research of Preprocess Model of Supervised safety Information of Coal Mine

From building up a supervised safety information system of coal mine,which has charac-teritics such as rapid speed,high efficiency,correct and reliability, the paper analyzed the necessity and feasibility of optimum transmission,set up a preprocess model of supervised safety information of coal mine by utilizing distributed calculating ability of Intranet.The model was used in supervised safety information system in Huaibei Coal Mining Group,and achieved remarkable result.
