Abstract: With the development of the economy and the acceleration of urbanization, land use in goaf areas has become an important research topic in some cities.In order to make full use of land resources, some new construction projects are sited in goaf collapse areas, but due to informal mining, no geological and mining information is available plus without confirmed distributed scope of goaf, and mining scale, thickness and depth of ground water level are also uncertain.In recent years, geophysical exploration techniques have developed rapidly, and the exploration techniques for goaf are becoming more and more diversified.Therefore, it is necessary to use a combination of a variety of geophysical exploration and drilling verification.In this paper, high-density resistivity method, and shallow seismic reflection wave method are adopted to carry out geophysical exploration for a construction project in Zaozhuang, Shandong Province, identifying the characteristics of goaf.The two methods complement and verify each other, effectively identifying the abnormal morphology of small coal mine goaf and delineating the sites of goaf.
