Abstract: Mineral resources exploration in covered area is an important component of the new round of prospecting breakthrough strategy. It is urgent to summarize and popularize prospecting in covered areas to quickly obtain the information and samples of buried bedrocks through more green and effective drilling technology. Based on the concept of green exploration, this study uses portable shallow drilling equipment and air reverse circulation drilling technique to carry out drilling tests in the exploration of copper polymetallic deposits in the shallow covered area of Baoshan, southeast margin of Daxinganling Mountains, realizing the effect of quickly penetrating the cover layer to obtain the information of hidden bedrocks, verifying geophysical anomalies and collecting geochemical samples. The in-hole imaging technique is simultaneously combined to provide the basic data for distribution range and boundary of the buried lithostratigraphic units in covered areas. The test results show that the multi-method combination based on shallow green drilling technology and in-hole imaging, which provide test samples for rapid field geochemical analysis, can effectively solve the prospecting problem in shallow covered areas, with good promotion value in the process of mineral exploration.
