Abstract:This paper put forward the importance of mine price forecast for the mining enterprises,research and predict the mine price trend.We analysis and forecast the annual average price of silver ore based on the gray system GM (1,1) model and the model of Verhulst,analysis of contrast predicted results,it is concluded that the GM(1,1) is suitable for ore price forecasting,price match degree is higher,predicted results provide reliable source of price information for the mining enterprises and the government.
Keywords:Mine price  GM (1  1) model  The model of Verhulst  Price forecast
