Based on the advantages of professional and core technology, Beijing China Coal proposes the service model of "Science and Technology Party B", which solves a large number of "stuck neck" technical problems in special well sinking by providing products and services with higher technology content, unleashing the scientific and technological efficiency of new quality productive forces, and leading the development of special construction technology of underground engineering in China. "Science and Technology Party B" realizes value creation with technical strength, and its main service products include freezing technology, grouting technology, drilling technology and equipment, Intelligent mine design and construction, and National Major Water Diversion Technology Services. "Science and Technology Party B" is a provider of technology + equipment + engineering overall solutions, and its ability to study and solve new technical problems in real time is more prominent in the implementation process, which has been tested in practice in the ground directional drilling pre-grouting project and water inrush emergency rescue and water plugging project of the Yellow River Diversion Project in central Shanxi Province.
