Study of Robust Determining Parameters Model for Probability-integral Method and its Application

Applying the Robust estimation theory to determining the prediction parameters of mining subsidence, the authors advanced the robust determining parameters model for probability integral method and designed corresponding computer program. A determining parameter test in artificial blunder disturbance was made on the actual mining subsidence observation data in Fengfeng mining district. The test results show that the technique of robust determining parameters can reduce the disturbance of blunders, overcome the iteration divergence problem in normal least squares fitting method and ensure the prediction parameters reliability and robustness.
