| Abstract:Replacement of trenching with drilling is effective technical means to solve the conflict between mineral exploration and ecological environment protection in the overburden zone. In view of the problems with shallow sampling technology in the overburden zone, with review of the advanced portable sampling drilling equipment and technology for surface exploration at home and abroad, and taking into account of the requirements of ecological civilization construction and green exploration, small angle （≤30°） drilling technology has been researched and applied successfully. |
