摘要为有效预测地下采矿诱发山区顺层斜坡的沉陷变形，在分析概率积分法水平地表开采沉陷的基础上，以与岩层、矿体的倾角相同或者相近的顺层岩质坡体为研究对象，建立单元体开采和半无限开采情况下顺层岩质倾斜地表的开采下沉变形预测模型，并给出预测模型的解算过程及步骤。通过2个矿山开采沉陷实例，将预测模型的解算结果分别与现场实测数据、相似模拟试验观测数据进行对比分析，结果表明：预测结果与现场实测下沉量吻合良好，与相似模拟试验观测下沉曲线形状相似，最大下沉量基本一致，符合试验原型的实际情况，预测结果能够反映顺层倾斜地表开采沉陷的情况，预测模型具有较好的适用性。

Abstract：The bedding rock slope was studied in order to effectively predict its deformation and failure induced by underground mining in mountainous area based on the probabilistic integration on mining subsidence of horizontal surface. A model for predicting the subsidence and deformation of bedding rock slopes was established under the condition of unit mining and semi-infinite mining and a calculation process was presented. The predicted results were compared with the data from field test and physical modelling test. The predicted results are in good agreement with the measured data of subsidence. The shape of the predicted subsidence curve is similar to that from the physical modelling test and they have the same maximum values of subsidence.

Key words： mining engineering mining subsidence bedding rock slope subsidence prediction model inclined surface
