| 摘 要： | 针对传统概率积分法求参程度仅适用于单工作面拟合求参的局限性和地表移动观测误差对参数精度的影响，提出了多工作面条件下求取概率积分计算参数的方法，并提出了观测粗差的识别方法，通过加权求参数油较大程度地减小发观测粗差对求参精度的影响，增大了求参程度的适用范围。

| 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. |
