Establishment of Accident Risk Early-Warning Macroscopic Model on Ventilation, Gas, Dust and Fire in Coal Mine

Based on the accident prevention of ventilation, dust, gas and fire in coal mines, and the risk early-warning theory of accidents, the risk early-warning principle is promoted. Then according to the principle and organization, combining the minds of safety scientific theory, cybernetics, information theory, decision theory and systems theory, using the computer technology, the macroscopic model of risk early-warning on ventilation, gas, dust and fire in coal mines is established. Then, it analyzed and introduced the process of detection, identification, early-warning analysis, early-warning signal distribution, and early-warning measures in the model. Finally, it developed a risk early-warning management information system on coal mine accidents by the model.
