The company won the

Recently, as a typical project of well construction project, the first phase of infrastructure construction project, which is a combination of exploration, construction and mining in the southeast mining area of qianbixi copper mine, the company has actively used advanced equipment, technology and technology to ensure the progress and safety. On the basis of strict quality control, obvious practical effect and comprehensive excellence, it was rated as the 2017-2018 China non ferrous metal industry (ministerial level) high quality project Cheng.

The first phase of infrastructure project of exploration and construction of Qianbi West southeast orebody is a milestone for Tongguan mine construction company to move towards overseas mine construction, and it is also one of the bases for Tongguan mine to establish its foothold in overseas market. In the construction process of the shaft excavation and masonry project, the company adopts advanced technologies and technologies such as high-pressure rotary jet grouting pile technology, rapid construction technology of shaft mechanized production line, curtain grouting of complex aquifer and grouting behind the wall to block water, assembly and hoisting technology of large steel structure derrick in narrow and small site, precise measurement technology of deep shaft equipment installation, etc., and mining during derrick installation The main shaft derrick hoisting technology, large-scale mechanical and electrical equipment (crusher) installation technology, manganese steel plate rapid installation technology in the ore bin, and reverse drilling construction pass through the crushing ore belt technology are carried out by using the double mast hoisting method. While greatly improving the work efficiency and saving the work period, the quality management and actual effect have achieved excellent results.
