| 摘 要： | 根据宜昌磷矿开采引起上部地表变形及岩体开裂的工程实际情况，在实测资料统计分析基础上，建立了高陡山区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。利用该模型对宜昌磷矿区开采引起岩体变形及山体失稳现象进行了分析。通过工程实例分析表明，理论预计结果与现场实测结果吻合。

| Abstract: | The prediction of rock mass displacement and their surface effects is an important problem of the rock mass mechanics in the excavation activities especially the metal and nonmetal mining in mountain areas. Based on results of the statistical analysis of a large amount of measured data in mining engineering, the fundamental theoretical model of ground surface movements due to underground mining is established by using the theory of probability. The formulas of rock mass displacements and deformations are developed and applied to the prediction of the ground surface movements due to underground mining in Yi-chang mining areas. The agreement of the theoretical results with the field measurements shows that our model is satisfactory and the formulae obtained are valid and thus can be effectively used for predicting the movements and the natural slope failure due to underground mining of phosphorus ore-deposit in mountain areas. |
