Study on Checking Hidden Danger Information Flow of Coal Mining

If the complicated system wants to be good running, it should have a stable initial condition. The function of checking hidden danger information system of the coal mine´s production in the accident control becomes more and more important. Taking tunneling waking face, we established the checking hidden danger information flow by stages, based on systems´ characteristics: Initial condition dependence, scale-up effect and long distance relatedness. It covered two evaluation systems, which are shift relief evaluation and work stage evaluation.
