Take the issue of optimizing paraments of the extraction unit as the background, according to the effect of the extraction unit on evaluation indexes of safety production, optimization model of which is established. First, two-parameter optimization model is established, accoding to evaluation indexes such as yield, efficiency and benefit, and for the joint distribution charateristics of the parameters. Second, according to toncoal cost, the model has been established, by fractional and polynimial function. Third, for the two-parameter optimization model is nonlinear unconstrained optimization problem, the model has been solved by adopting the DFP method, according to the charateristic of which, and the optimization result matches pratical case. Finally, analyze and evaluate its result. And the quantitative prediction is carried out according to the parameter model of the extraction unit
