In solid mineral exploration， the complex terrain of the work area poses significant challenges to the relocation of drilling equipment， and building roads or manual relocation involves high workload， long construction period， substantial environmental damage， and high safety risks. Taking the Chenjialun survey area in Anhua County， Hunan Province， and the Majiangyuan survey area in Jianghua County as examples， three types of multi-rotor drones were selected， and attention was taken on comparative analysis of the drone hoisting and transporting processes such as equipment disassembly and bundling， route planning， and flight hoisting， as well as their application effects. The application results show that drone relocation has advantages such as high efficiency， low labor intensity， and environmental friendliness. Compared with the traditional relocation methods， it contributes to the realization of green exploration. At the same time， suggestions were put forward in terms of enhancing the load-carrying and endurance capabilities of drones， improving the multi-control mode of drones， and optimizing the modular distribution and integration of drills. The advantages and application effects of multi-rotor drones under complex terrain conditions can provide useful reference for the relocation of drilling equipment in areas with complex terrain.
