<p>With the deepening of the construction of ecological civilization and the continuous growth of the demand for mineral resources, the research and promotion of green exploration equipment and technical methods is the goal of the healthy and sustainable development of geological work. This paper systematically reviews the latest progress of domestic green exploration geological core drilling technology. The advantages of low-carbon and high-efficiency drilling technology such as directional drilling, drilling instead of trench, air reverse circulation drilling, rope hydraulic impact drilling, environmental protection flushing fluid, and discusses the applicability of related drilling equipment and technology in different scenarios. China’s green exploration equipment and technology system has been initially formed, but there are still problems such as insufficient research and development and promotion of automation equipment, bottlenecks in directional coring technology, and inapplicability of industry standards and related technologies. Therefore, this paper puts forward some suggestions, such as strengthening the research and development and promotion of automatic ( intelligent ) drilling equipment, innovating environmental protection flushing fluid and waste slurry treatment technology, and improving geological exploration norms, so as to promote the high-quality development of geological exploration industry in the direction of green, intelligent and efficient.</p>
