    Abstract:

    It is very important to select type of mine drainage pump for designer to draw the characteristics curve accurately.The method of the characteristics curve fitting was analyzed basing on Least square method,Lagrange interpolation method and Newton Interpolation method.The results showed that Least square method is much more exactly,Newton Interpolation method is much more convenient,and the simplest method is Lagrange interpolation method.
