en.Wedoany.com Reported - In early June 2026, two scientific and technological achievements of Shougang Group Co., Ltd. Mining Company passed evaluation by authoritative experts and were recognized as reaching the international leading level overall. These two achievements are "High Ore Pass Disaster Prevention and Functional Reconstruction Technology" and "Intelligent Centralized Control System for Ultra-Large Concentrator," evaluated by review committees led by multiple academicians, setting benchmarks for deep mine disaster management and intelligent transformation of large-scale concentrators.
Shougang Mining Company is the core raw material base under Shougang Group, headquartered in Qian'an City, Hebei Province. It is one of China's extra-large ferrous metal mining enterprises, with an annual production capacity of 22 million tons of iron concentrate powder. The two recognized achievements focus on mine safety production and intelligent upgrading. Among them, the "Key Technology and Application of Strong Inrush Disaster Prevention and Functional Reconstruction of High Ore Pass" was led by Shougang Mining Tangshouma Iron Mine, addressing the coupling challenge of "high stress, high water pressure, and dynamic load impact" faced by high main ore passes in underground metal mines. This project innovated a collaborative governance model of "cutting-off, plugging, and reconstruction," and developed composite grouting materials and a three-dimensional water control process. Through the application of this technology, the measured water inflow of the ore pass significantly decreased from 5.74 cubic meters per hour before treatment to 0.6 cubic meters per hour, a reduction of nearly 90%.
Another achievement is the "Intelligent Centralized Control System for Ultra-Large Concentrator." This system successfully addresses pain points such as lagging indicator detection and intensive manual operations in traditional beneficiation processes, establishing a closed-loop intelligent control system covering the entire process. The system has achieved unmanned stable operation in a concentrator with an annual output of 22 million tons, effectively supporting Shougang Mining's essential safety management goal of "replacing manual labor with automation and reducing personnel through intelligence." By deeply integrating 5G private networks and AI intelligent platforms, the system enables remote surface control of 74 sets of key equipment across 7 categories, with an operation accuracy exceeding 90%.
These two achievements have not only demonstrated significant application effects in domestic mines but also provide replicable technical examples for deep mine disaster management and intelligent transformation of large-scale concentrators both domestically and internationally.
