en.Wedoany.com Reported - On April 27, the performance evaluation meeting for the National Key R&D Program project "Key Technologies and Equipment for Kilometer-Level Shaft Hard Rock Full-face Tunnel Boring MachineKey Technology" led by China Railway Construction Heavy Industry Corporation Limited was held in Anshan, Liaoning. The project team presented an overall report to the expert panel and addressed inquiries and discussions, based on the task document requirements and centered on the key technical indicators, innovation achievements, and application value of the boring machine project. As an important project for China's deep resource development equipment research and development, the boring machine project received a comprehensive review from the expert panel at the evaluation meeting.

The expert panel carefully reviewed the technical materials and achievement reports for each subtask. Through a comprehensive assessment, the expert panel unanimously agreed that the "Key Technologies and Equipment for Kilometer-Level Shaft Hard Rock Full-face Tunnel Boring Machine" project had completed all required tasks, with technical indicators reaching expected goals, strong originality in technology, and broad application prospects. The project involved collaborative research across 10 entities, including the University of Science and Technology Beijing, China University of Mining and Technology-Beijing, and Ansteel Mining Group Co., Ltd. This review process also encompassed guiding opinions on the subsequent project completion procedures and documentation refinement, providing important support for the formal project completion phase.

The evaluation results show that the "Steel Backbone" equipment developed by this boring machine project has filled a technological gap in its field. The expert panel's recognition signifies that the equipment has gained important acknowledgment for its technical maturity. The passing of this performance evaluation lays a solid foundation for the subsequent project final acceptance and technology promotion. This equipment achievement will provide core equipment support for deep mineral resource development and underground space utilization. With the project officially passing the subtask performance evaluation, the independently developed core equipment will expedite its promotion and application into the field of deep earth engineering.
