Grey Forecasting of Hazards for Mine Enterprise
The principle and characteristics of grey model are studied in this paper. The dynamic model GM(1,1) in the form of differential equation are modeled and used to forecast the hazards of Zhongtiaoshan Nonferrous Metal Corp. in Shanxi Province. A middle long term forecasting model for the occurrence of hazards is established. In order to improve the forecasting precision of mine hazards, by introducing Markov chains forecasting method, a grey-Markov model for forecasting mine hazards is established based on grey forecasting method. The model combines the advantages of both grey forecasting method and Markov chains forecasting method, overcomes the influence of random fluctuation data on forecasting precision and widens the application scope of the grey forecasting. An application example is conducted to evaluate the grey-Markov model, which shows that the precision of the grey-Markov model is better than that of grey model in forecasting mine hazards.
