摘要
简单介绍了浅层地震和瞬变电磁技术在探测采空区的原理,并根据2种方法各自的特点,综合确定了某矿上组煤层的采空异常区和积水异常区。经井下验证,证实物探结果准确,说明通过综合物探勘查方法,可以为下组煤的安全回采提供保障。
This paper introduced the principles of shallow earthquake and transient electromagnetic technology in exploring gob. Combining characteristics of two methods, gob anomaly area and water anomaly area of upper coal-seam in a mine were ob- tained. Underground checking verified geophysical results. This showed that comprehensive geophysical method could provide security for mining lower coal-seam.
