In an open-pit coal mine in Inner Mongolia, photovoltaic pile driving technology has been innovatively applied to slope treatment projects. The construction team used a retractable pile driving platform to install photovoltaic support foundation piles on the mine wall with a slope of 45 degrees. By using unmanned aerial vehicles to survey and generate a three-dimensional terrain model, the system automatically plans the optimal pile position and cooperates with a remote-controlled pile driver to complete the operation. It can install 200 pile foundations in a single day.

The person in charge of the ecological restoration project stated that this technology combines photovoltaic power generation with mine management, utilizing abandoned mine space to construct photovoltaic power stations and reinforcing slopes through pile foundation networks to prevent soil erosion. At present, the project has installed 500000 square meters of photovoltaic panels, with an annual power generation of 120 million kilowatt hours, while reducing mine dust by more than 90%. This "photovoltaic+ecological restoration" model is being promoted in more than 20 abandoned mining areas across the country.
