摘要： 济南章丘市一处拟建厂房场区，经钻探和物探综合探查基本确定了采空区的分布范围，后采用注浆方法进行了地基处理。注浆孔主要布置在采空区范围内，并且在发生掉钻或漏水的注浆孔周围加密布置。统计注浆孔钻进状况，总结了注浆孔耗浆量与钻进异常之间的对应关系，并对注浆质量的抽芯检测和揭露“结石体”的特征进行了总结，取得了一定的工程实践经验。

Abstract: The proposed industrial buildings in Zhangqiu City, Jinan, are located above an abandoned mine. The limits of the underground voids were determined throughout the conventional boring program and geophysical methods. The compaction grout was used for the abandoned mine voids treatment. The grouting holes primarily located within the void limits. At locations with drill bits lost and drilling water loss, grouting holes were more densely distributed. The relationship between the penetration rate of the grouting holes and the grouting quantities were statistically evaluated. The coring of the grouting column was used as a grouting quality assurance measure.
