Abstract: Green exploration technology is an important measure to support the new round of prospecting breakthrough strategy and practice the concept of green development. Drilling is one of the technical means to objectively obtain underground physical data, and it is also considered to be the most significant technical type of environmental damage among many exploration means. The negative impact of drilling construction on the environment can be systematically summarized as the following three points. Firstly, the physical disturbance to the surface environment. Secondly, the chemical element pollution to the rock formation and water body within a certain depth of the surface or underground. Thirdly, the noise and exhaust emissions during the operation of drilling equipment. In response to the above three environmental problems, based on the depth distribution characteristics of nearly 1.2 million geological survey drill holes in the country and the direction of the new round of prospecting breakthrough strategy to break through the exploration, drilling technology should be at least in the light and modularization of mechanical equipment, the selection of drilling circulation media types and the harmless treatment of waste, and the driving force of mechanical equipment, in order to reduce the physical disturbance, reduce chemical pollution, control noise and exhaust emissions, improve drilling efficiency and automation. In addition, the drilling of mineral exploration should also use other technologies, such as in-hole imaging technology, through the collection of in-situ geological information such as lithology, structure and occurrence shown in the hole wall, to improve the utilization of boreholes, and then improve the level of green exploration.
