According to the requirements of promoting green exploration and constructing a modern equipment system that integrates ecological protection and mineral exploration breakthroughs， this paper explores the application of modular drilling technology using unmanned aerial vehicles （UAVs） for typical forest covered terrain in southern regions. The performance and suitability analysis of TF-500 series heavy-lift unmanned helicopter systems and ZY-800P portable fully hydraulic modular drilling rigs are conducted， focusing on their application in the detailed exploration of gold deposits in the Yueguangchong Mine Area， Xinhua County， Hunan Province. This technology demonstrates outstanding environmental adaptability and practicality， utilizing UAVs’ flight capabilities for efficient， precise hoisting and transportation of drilling equipment， significantly shortening the relocation cycle， minimizing ecological impact， and enhancing operational safety and efficiency.
