摘要(Abstract)：

崩塌灾害具有高隐蔽性、强突发性、重危害性等特点，其预警监测是各类重大基础工程准备阶段以及施工期间的重要研究工作，同时也是崩塌临灾监测救援现场指挥工作的重要科学依据。结合地基合成孔径干涉雷达技术(GB-InSAR)和最新的MIMO技术，将应急边坡救援雷达S-SARⅡ的系统量程扩大了60倍，并通过监测内蒙古某矿场主矿坑西南帮崩塌隐患点生成雷达形变图，结合三维高程模型DEM以及多种预测模型预测崩塌发生时间。结果表明，S-SARⅡ精准地确定了形变区域及形变量，并预测崩塌发生时间为8月29日9∶32-10∶27之间，最终崩塌发生时间为8月29日10点26分。因此，S-SARⅡ准确预测了崩塌灾害的发生时间，最大程度地保障了矿区的生产安全，并通过实际应用分析证明，优化后的S-SARⅡ的系统量程得到了数量级提升，满足崩塌监测的需要，且以S-SARⅡ为代表的遥测预警技术在地质灾害险情处置和应急救援中具有明显的技术优势。
