Recently, Xinlong Mining has achieved another success in mining construction—the ventilation shaft construction project of the 113 line, 30 middle section of the 630 pit mouth, successfully achieved precise penetration with a diameter of 2 meters. This breakthrough of the “key node” not only marks a new height in the mechanized construction technology of Xinlong Mining under complex deep geological conditions, but also directly promotes the mechanized team to complete the ability upgrade of “technology + equipment + talent.”

01 Tackling difficulties, challenges emerge
This ventilation shaft construction project was like a “tough battle”, facing many “obstacles” such as complex geology and difficult transportation. Firstly, the pit mouth terrain is complex and the passage is narrow, making the transportation of large equipment extremely difficult; secondly, the shaft diameter is 2 meters, requiring extremely high precision and safety control in construction, and any slight carelessness can easily lead to deviation or collapse;

02 Professional escort, double insurance
Faced with numerous difficulties, Yier Technology acted quickly, sending after-sales engineers to provide on-site guidance, and jointly formed a “technology + construction” joint task force with Xinlong Mining, injecting strong technical strength into the project. Before the construction, the technical team conducted a comprehensive and in-depth survey of the construction site, fully grasping the geological conditions, surrounding environment, and potential risk points. Based on this, a project construction plan of “layered advancement + dynamic monitoring” was tailored, clarifying the construction steps, technical requirements, and quality control standards. At the same time, detailed contingency plans were developed for potential equipment failures, geological changes, and other risks to ensure that emergencies could be handled quickly and effectively.
Mechanical operation, quality and safety dual control

In this shaft construction, Xinlong Mining used Yier Technology AT-2000 Raise borer Machine to replace manual shaft construction, with mechanized construction as the core driving force. This equipment, with its high-precision positioning system and adaptive rock layer cutting technology, demonstrated excellent performance under complex geological conditions, with a single-shift operation efficiency 200% higher than traditional manual methods. The well wall is smooth after the shaft is formed, with minimal disturbance and damage to the surrounding rock, resulting in high-quality well formation. This not only effectively avoids safety risks such as falling rocks, water leakage, and toxic gases, but also greatly reduces labor intensity, shortens the construction period, and improves construction safety and efficiency. With the joint efforts of all staff, the project progressed rapidly. From March 29th to April 5th, the pilot hole construction was successfully completed in only 7 shifts; from April 14th to April 20th, after 11 shifts of hard work, the reaming was completed and the penetration was successfully achieved, demonstrating the company’s strong technical strength and excellent management level in shaft construction under complex deep geological conditions.
Significant achievements, quality and safety dual control

The successful penetration of this shaft is of great significance, as it will effectively improve the ventilation and drainage conditions of the working face below the 30 middle section of the 630 pit mouth, providing a solid guarantee for safe underground operations. In addition, the successful introduction and application of the Raise borer Machine by Xinlong Mining marks a leap-forward transformation of shaft construction from traditional manual methods to mechanized, automated, and intelligent construction. It also accumulates experience for subsequent roadway excavation, equipment installation, and other projects, effectively promoting the smooth progress of the entire project and contributing to the construction and technological upgrading of the mine’s mechanized team.

Looking to the future, Yier Technology will continue to explore innovation and deepen the application of mechanized, automated, and intelligent technologies in mining construction to contribute to the high-quality development of the mining industry.
