Closure of the headframe cap of the auxiliary shaft at Datuhe Coal Mine in Shanxi Province.

At 9:00 a.m. on April 29, 2026, colorful smoke rose into the sky and ceremonial cannons boomed as the closing ceremony for the headframe of the auxiliary shaft at Shanxi Datuhe Coal Industry Co., Ltd. officially commenced. Around 10:00 a.m., under the precise operation of a 500‑ton crawler‑type heavy‑lift crane, the headframe of the auxiliary shaft was seamlessly joined at an altitude of several dozen meters, achieving millimeter‑level precision in the final alignment of the massive 51.5‑meter‑tall structure.
Zhao Kanghong, General Manager of the Group; He Jichun, Chief Engineer; Qiu Jiaoxi, Assistant to the General Manager; Feng Yunwang, Secretary of the Party Committee of Datuhe Coal Industry; and relevant leaders from the Installation Division of China National Coal Construction Group No. 3 attended the site, joining representatives from the project owner, the contractor, and the supervision unit to witness this milestone achievement and celebrate the successful completion of the project.
As the core and critical structure of a mine’s hoisting system, the auxiliary shaft headframe performs vital functions such as personnel transport, material handling, and equipment maintenance. It features a complex structural design, substantial dimensions, and stringent installation standards. Lifting operations are characterized by frequent high‑altitude work, demanding coordination, and concentrated safety risks, making this one of the most challenging and closely monitored key projects in the construction of the auxiliary shaft.
Since construction began at the end of February this year, despite multiple challenges—including an extremely confined site and difficult access roads—workers pressed forward against the odds, toiling day and night. They completed the milestone task 12 days ahead of schedule and to a high standard, delivering a decisive victory in this critical phase. This marks the entry of Datuhe Coal Industry’s hoisting system installation into its crucial stage, representing another major step forward in the mine’s construction project.
Since the project’s commencement, both the mine and the project office have confronted challenges such as tight deadlines and high‑risk work at height, promptly establishing a dedicated task force to tackle these issues. Drawing on site conditions, they meticulously developed construction plans, adopted a reverse‑schedule approach with visual progress tracking, and broke down tasks down to the daily level, assigning clear responsibilities to individual team members—laying a solid managerial foundation for efficient advancement. All personnel involved embraced a spirit of relentless determination, working tirelessly to overcome adverse weather conditions and maintaining a sustained, high‑intensity pace on site. The technical team provided continuous oversight of every process, from millimeter‑level verification during foundation acceptance and repeated checks during component pre‑assembly to simulation of lifting parameters, ensuring that each stage rigorously adhered to technical specifications and quality standards: “No item failing to meet requirements shall proceed to the next step.” During the critical hoisting of the second section of the main incline—weighing over 180 tons—the command, crane operators, and inspection teams coordinated seamlessly, achieving successful one‑time placement and attaining alignment tolerances far below design requirements.
The builders have ensured quality through meticulous attention to detail and maintained safety with stringent measures, achieving zero accidents throughout the entire project. With a 100% pass rate in project acceptance, they have earned unanimous recognition from both the supervising engineers and the client, tirelessly striving to deliver a benchmark‑setting, high‑quality project.
During the construction phase, Mine Manager Sun Jianwei personally visited the site on multiple occasions to oversee and coordinate operations, convened numerous specialized meetings to address practical issues, and ensured seamless collaboration across all departments, enabling targeted efforts that laid a solid foundation for the timely completion of key project milestones.
The distinguished leaders extended their warm congratulations on the successful completion of the permanent headframe project at the auxiliary shaft, fully commended the project’s achievements, and expressed their sincere appreciation to all participating units and frontline construction personnel. They noted that the smooth completion of this project has laid a solid foundation for Datuhe Coal Industry’s subsequent production and development, and urged the company to take this milestone as a new starting point, continuously strengthen its safety‑production framework, and steadily advance the implementation of all key projects. Furthermore, they called on all parties to maintain the positive momentum of close and sincere cooperation, pool their strengths for shared development, and make every effort to enhance the quality and efficiency of all mine operations, thereby supporting the enterprise’s sustained and sound growth.
The timely and successful completion of this derrick‑erection project fully exemplifies the “iron‑troop” spirit of the China National Coal Machinery Installation Project Department—characterized by extraordinary resilience, unwavering combat readiness, and a profound commitment to dedication—and underscores its steadfast adherence to the construction principle of “safety first, quality paramount.” The precise closure of the auxiliary shaft derrick marks a significant achievement resulting from the concerted efforts and pragmatic problem‑solving of the entire project team. Moreover, it represents a pivotal transition in the mine’s infrastructure development, shifting from civil engineering to mechanical and electrical installation and system integration. This milestone effectively clears the critical pathway for subsequent work, creating the necessary preconditions for the orderly advancement of a series of operations—including head‑sheave installation, cage‑guide‑rail laying, hoisting‑equipment commissioning, and the refinement of underground auxiliary systems—thereby accelerating the overall pace of mine construction.
In accordance with the project construction plan, the mine and the project management team will unite and forge ahead, seize the momentum, and sustain the vigorous work ethic. They will steadily advance the subsequent installation and commissioning of the auxiliary shaft hoisting system, ensuring timely, safe, and high-quality delivery by the end of 2026, thereby making a greater contribution to the early completion and commissioning of the mine and to the company’s high‑quality development.
