Abstract	Gob represents poor engineering geology for expressway construction in mine areas, especially that small coal mines and old mines are mostly mined earlier privately or collectively without complete geological or mining data, therefore, seeking highly accurate, economical and practical gob detection technology to identify in detail the actual situation of gobs under expressways and provide high-quality exploration results will be directly related to the quality and economic efficiency of expressway construction. Upon the analysis on current exploration and research of gobs under expressways, the author introduces an effective way to detect small coal mine gobs under expressways — detection technology of high resolution earth resistivity. And the technology has been applied for exploring gobs under an expressway. Drilling verification shows that the exploration results are reliable, accurate, and had played an important role in guiding gob control, design and construction.
