摘要： 结合某地具体的工程实例，根据场地的岩土工程条件对场地局部区域进行了施工勘察，分析出采空区的特点，拟定了注浆法对采空区进行处理。然后阐述了注浆处理具体设计的各种要求以及对参数的确定，详细分析了在处理过程中遇到的三个孔异常情况处理的方法。施工完后，采用点、面相结合的方法进行质量检测。根据检测孔布置图，经过钻孔、压水试验、跨孔CT扫描技术的效果检测，所得检测结果均达到预期的注浆效果。

Abstract: This paper presents a case history of the mined area treatment of a coal mine.  The design grouting scheme for the treatment was selected based on the specific conditions of the mined area and the site subsurface conditions. Details of the grouting design and the measures for dealing with the adverse conditions during the grouting process are also introduced. The test boring, water pumping and crosshole CT scanning techniques were used to verified the grouting results. The testing results indicated that the goals were achieved.
