摘要
将稳健估计理论应用于矿山开采沉陷预计参数的求取 ,建立了概率积分法稳健求参数学模型 ,并编制了相应的稳健求参计算软件。利用峰峰矿区开采沉陷实测资料进行人工异值干扰求参实验 ,结果表明 ,采用稳健求参技术可降低异值或粗差的干扰 ,克服常规的最小二乘法拟合求参时常出现的结果发散问题 ,保证了求参结果的可靠性和稳健性。
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.
