摘要: 概率积分法在开采沉陷预计方面应用广泛,但预计结果的准确性在很大程度上取决于概率积分法预计参数的可靠性。文章使用数学优化计算软件1stOpt,探讨了概率积分法预计参数的反演方法,并用实例进行了分析验证。结果表明:该方法操作简单,计算准确性较高,且不需要预先给定初始经验值,大大降低了求取概率积分法预计参数的复杂性。

Abstract: Probability integration method has extensive application in mining subsidence prediction, while the accuracy of result mostly depends on the reliability of the parameters. This paper has a discuss on the inversion method for getting the predicting parameters using the calculation software 1stOpt for mathematical optimization, and then this method is carried out by three examples. The result shows that this method ,with simple operation and high accuracy, need not the initial value and greatly reduces the difficulty in getting the parameters.
