摘　　要：针对无底柱分段崩落法的采矿特点,把概率积分法引入金属矿山开采沉陷预测中,并通过模型修正提高预测精度。利用GIS强大的图形表现力和空间分析能力实现开采沉陷预测的可视化,能够直观掌握开采沉陷对周围环境的影响程度及范围。通过将预测结果与地表观测数据及实际情况的对比分析,验证了此预测方法的适用性。In light of the characteristics of Nonpillar sublevel caving method, Probability integral method is used to predict mining subsidence and modified to improve predicting accuracy. By using the drawing too.Is and the effective spatial analytical function of GIS, the degree and scope of mining subsidence are intuitively shown. By a comparison with the observation data of the ground surface and actual situation, the proposed approach has been verified.
