1. Compile vector diagram and three-dimensional model of underground roadway: Images and models can provide intuitive reference for mining planning and design, and can also be used for geological prediction and fault analysis, which is helpful to avoid mine accidents.

2. Underground roadway deformation monitoring and groundwater level measurement: understand roadway deformation and groundwater gushing, and prevent geological disasters and flood accidents.

3. Navigation and location of underground mining: Setting measuring equipment and sensors in underground roadway can monitor the positions of personnel and equipment in real time and improve the safety and production efficiency of miners.
