摘要
概率积分法预计的基本参数值选取的准确与否直接关系到矿区地表移动和变形预计的精度。针对目前无实测资料或特殊地质采矿条件下的矿区沉陷预计参数选取缺乏理论依据的现状,详细分析了地质采矿因素对概率积分法参数的影响机理,并结合大量文献,总结了概率积分法参数的影响因素。
The value of parameters of probability integral method directly influence on the prediction accuracy of surface movement and deformation. In view of lack of theoretical basis when selecting prediction parameters in mining area with no measured data or special geological and mining conditions, the influence mechanism of geologic and mining factors to probability integral method parameters is analyzed and influencing factors to probability integral method parameters are summarized on the basis of a great amount of literature.
