The Government of Uzbekistan planned to develop Shargun Coal Mine Technology Renovation Project, in Viloyati, Surxondaryo, Uzbekistan. The consortium of China Coal Technology & Engineering Group and China Railway Tunnel Group was the EPC contractor of the project. Zhongyun International Engineering Co Ltd is the design consultant of the project. The construction of the project mainly included the renovation work of the coal mine, the tunnel excavation work, and some other work. The project was expected to help the mine increase its capacity from 160000 t/y to 900000 t/y. The mine was originally completed and put into operation in 1958. After Uzbekistan became independent in 1991, the mine's production capacity had gradually shrunk. Currently, underground production was suspended. Upon the project's completion, the project would become the first modern coal mine renovation project in Uzbekistan.
