摘　　要：本文在南桐采煤沉陷区运用EH-4电磁成像系统寻找地下水富水区域,得到以下结论:探测出Ⅳ号异常区域含水充分,Ⅲ号区域T1f6-7层位的中、下段遭受地下采煤的破坏影响有限。其中Ⅳ号异常区域位于拉伸区,经钻孔验证出水量大且稳定,论证了Ⅳ号异常区域是研究区较好的取水地段。本次EH-4电磁成像系统探测出的地下水富集区域与采空区位置均与实际吻合,说明EH-4电磁测深测量技术是岩溶区域采煤沉陷区寻找地下水的有效方法。In this paper, EH-4 electromagnetic imaging system is applied to search groundwater-rich area in Nantong coal mining subsidence,conclusions list as follows：Layer T1f6-7 in section No. Ⅲ is barely influenced by underground mining. NO. Ⅳ abnormal section, located in stretched area, is detected as watersufficient area. Groundwater-rich region detected by the EH-4 electromagnetic imaging system fits in with the actual subsidence position,which proves EH-4 electromagnetic sounding measurement techniques to be effective methods to search groundwater in karst coal mining subsidence.
