Coal Mine Gas Emission Gray Dynamic Prediction.

Abstract: This paper introduces three kinds of mathematical prediction models: grey prediction, new information, and metabolism. The three prediction models were verified and analyzed by the example of the mine in Hegang, as a result, it is showed that the new information model predictions’ result was more accurate, the information model combines with the monitoring system can realize the dynamics of coal mine gas emission projections.
