摘　　要：在实测资料统计分析基础上,以概率理论为基础,建立了高陡山区房柱法地下开采岩体移动变形预测分析模型,并给出了岩体变形破坏的极限值。利用本模型对山区地下开采工程实例进行了具体的计算分析,通过工程实例分析说明,理论预测结果与现场实测结果吻合。Based on the results of statistical analysis of a large amount of measured data in mining engineering,the statistical model of rock mass displacement is established by using the statistical theory.The theoretical formulas are developed and applied to the prediction of the rock mass displacements and deformations due to underground mining by pillar-and-room method in mountain areas. The agreement of the theoretical results with the field measurements shows that the model is satisfactory and the formulae obtained are valid and thus that can be effectively used for predicting the movements and the natural slope failure due to underground mining by pillar-and-room method in mountain areas.
