Qulong Copper Polymetallic Deposits Tibet, China   Project The CNY 16.4 billion project required Changsha Design and Research Institute of Nonferrous Metallurgy (Changsha) to design and engineer a new mining preparation plant to exploit copper and molybdenum resources at Tibet’s Qulong Copper Polymetallic Deposit (Qulong). To guard against potential power failures at the highest altitude mine in the world, optimize productivity and resource utilization, realize environmental efficiencies, and ensure effective, multidiscipline collaboration and management throughout the plant’s lifecycle, Changsha needed to use flexible and interoperable modeling software. Solution Changsha implemented Bentley’s integrated BIM solutions using ProjectWise for multidiscipline collaboration, MicroStation for 3D plant design of workshop schemes, AECOsim Building Designer to design the heating, ventilation, piping, and drainage systems, Bentley Raceway and Cable Management for electrical design, and Bentley Navigator to identify and resolve collisions prior to construction. The flexibility and interoperability of Bentley software enabled Changsha to produce a collaborative 3D design that could be used throughout the operation and maintenance of the plant for asset and risk management, production execution, and training.
