Abstract: Green geological exploration refers to the implementation of the concept of green development in the whole process of geological exploration, the use of efficient and environmentally friendly methods, technologies, processes and equipment, etc., to reduce or avoid adverse effects on the ecological environment, and to repair the disturbed environment, to achieve geological exploration, ecological environmental protection, community harmony and win-win results. Taking a lithium mine exploration project in Sichuan Province as an example, discusses the on-site management measures of green geological exploration in the aspects of resident construction and management, road construction and site leveling, drilling engineering construction, environmental restoration and so on, and uses the method of value analysis to carry out the technical and economic evaluation of green geological exploration drilling construction, and puts forward reasonable suggestions for the improvement of green geological exploration measures, so as to provide some experience that can be popularized or used for reference for the on-site management of green geological exploration in the same type area or similar type area.
