In the mineral exploration around the villages and towns， residential houses， farmland， roads， agricultural infrastructure， mountain vegetation and so on are usually encountered. In order to protect the ecological environment and meet the requirements of green exploration， in the detailed investigation of Xujiaqiao Black Talc Mine in Guangfeng， exploration was carried out by using technical equipment such as UAV aerial survey， portable full hydraulic core drills. With advanced equipment selection， environment-friendly technology， the proper exploration plan and specific environmental protection measures， the project has achieved the results of shortening the exploration period， improving core recovery， eliminating the typical exploration risk， reducing the labor intensity and cost of land requisition and relocation， and reducing the pollution and damage to the ecological environment； thus， realizing quality and efficient geological exploration with both good economic and social benefits， and achieving the goal and task of green exploration. Exploration of geology and mineral resources in the manner of green exploration not only protects the ecological environment of water and mountains， but also improves exploration efficiency and quality， reduces labor intensity and cost， and achieves the goal of energy saving and consumption reduction by use of high-standard green exploration technical means and environmental protection requirements. Green exploration is a sustainable and high-quality development road.
