This is a deep copper mine waste rock dump in Baiyin City, Gansu Province. As a resource-depleted city, Baiyin City has been striving to promote the restoration of the local ecological environment through scientific demonstration and precise policy implementation over the years in response to ecological damage problems left over from history such as deep copper mine waste rock dumps and tailings ponds, and constantly explore ways to green and sustainable development. Breakthrough.

At the end of 2019, CNNC Huineng signed a cooperation framework agreement with local enterprises to develop and construct a 100-megawatt photovoltaic power generation project in a deep copper mine waste rock yard, and promote the integration of ecological environment management and industrial development according to local conditions. The project will be completed and put into operation in February 2023 and will be connected to the grid to generate electricity.

Through the construction of photovoltaic projects in deep copper mine waste rock fields, new economic value has been generated in the originally abandoned mountainous areas. Each photovoltaic panel is like a huge "parasol", which can block light, cool down, and reduce surface water seepage. Through natural precipitation and ecological care, it is expected to gradually restore the damaged ecological environment and turn the former abandoned and polluted land into an "optical valley" with "surging" green electricity.

The 100-megawatt photovoltaic power generation project at the Baiyin Deep Copper Mine Waste Rock Site can save about 47,000 tons of standard coal every year. Through the "photovoltaic power generation + mine management" approach, the local area can achieve a win-win situation of ecological restoration and economic benefits.
