【Abstract】 The new methods of getting probability integral method parameters under the condition of multi working face and recognizing observation errors are put forward, which are directed against the traditional program localized to the single working face and the survey errors have much effect to the parameters precision. These methods greatly minish the effect of observation errors to the parameters precision and widen the suitful scope of parameter getting program.更多还原
