en.Wedoany.com Reported - The group standard "Technical Specification for Ground Pressure Investigation in Deep Metal Mine Mining" (T/CI1421-2026), led by the Deep Well Mining Laboratory of China's Shandong Gold Group, has been approved and simultaneously implemented by the China International Association for the Promotion of Science and Technology.
This standard unifies the technical basis for ground pressure investigation during deep mining in metal mines, specifying the classification of ground pressure hazards, investigation work content and procedures, rock mechanics investigation, rock mass deformation and failure investigation, support deformation and failure investigation, as well as technical requirements for ground pressure hazard risk classification and prevention. The specification applies to regional ground pressure investigation technical work in metal underground mines with mining depths exceeding 800 meters, providing support for the standardized and normalized development of mine ground pressure hazard prevention technologies.
The promulgation and implementation of this standard marks a phased progress by the Deep Well Mining Laboratory of Shandong Gold Group in the systematic management of deep mine ground pressure hazards. The Deep Well Mining Laboratory stated that it will continue to conduct technical research in the fields of deep ground pressure hazard monitoring, early warning, and prevention, providing technical support for the safe and efficient extraction of deep resources.
