The Research Of Forecast Of Mine Gas Emission

The gas is one of the most important factors that endangers the produce in mines without accident. It has very highly social and economic benefits to strengthen the forecast and the control over the gas in mines.The key of forecast is to obtain higher precision. At the only condition of high precision the forecast can posses real significance. And the key of to precision forecast is to analysis the influencing factors. The thesis,on the basis of correlative data from the historical coal,used Grey system theory and Fuzzy Math Theory and puts forward new ways that analysis the influencing factors. It founded new model through correlative analysis. The new model made properimprovement on data generating operation and parameter. By tests and verifying,the improved model can obtain higher precision. It possessed characters of easy calculating and procedure,too.The thesis made forecast on the gas of Daxing Mine of The TieFa Bureau,according to the forecast model,got detailed data. It provided valuable data for management to the gas. The thesis also drew some conclusions and suggestions on the researches for the subject.
