Influence of geological and engineering factors on mine gas emission is analyzed.Nonlinear regression method is proposed for forecast of mine gas emission.Influencing factors are first determined according to practical mine conditions
and then the nonlinear mathematical regression model is established and verified based on the nonlinear estimation module and the fixed nonlinear regression module of the STATISTICA software.It is found that gas emission has high correlation with influencing factors for the model.The nonlinear mine gas emission forecast software was developed based on advanced programming language C# and visual interface provided by.NET.The forecast result for No.3390 working face of Chengzhuang mine shows that it is feasible to forecast mine gas emission through nonlinear regression method.
