Recently, good news came from the underground mining project at Xinzhou Mining: relying on the ATM-600T small cutting Raise borer Machine independently developed by Yier Technology, the mine’s 600mm-diameter, 30m-deep cut shaft project achieved precise and smooth breakthrough. The quality of the completed shaft, construction efficiency, and operational safety all met the project’s expected standards, laying a solid equipment and engineering foundation for the mine’s subsequent block‑extraction operations. The ATM-600T small cutting Raise borer Machine used in this operation is a lightweight rock‑drilling device specially designed for narrow mine tunnels and low‑clearance chambers, perfectly suited to the complex underground construction conditions of small and medium-sized mines.

Lightweight custom design, tailored to complex downhole environments.
The ATM-600T cutting Raise borer Machine features a wheeled articulated design, comprising two major modules: the working power unit and the traveling unit. The entire machine weighs only 11 tons, with overall transport dimensions of 4.38 × 1.27 × 1.98 meters. Notably, its ultra-narrow transport width of 1.27 meters addresses the longstanding challenge of limited underground transfer for conventional cutting Raise borers, enabling seamless compatibility with various mine rampways and standard cage‑based underground transport requirements. This ensures flexible and efficient underground relocation without the need for additional equipment disassembly or roadway modifications, significantly reducing upfront preparation time and labor costs.

Dual-purpose, multi-condition operation—highly efficient, precise, cost‑saving, and productivity‑boosting.
At the equipment performance level, the ATM-600T compact Raise borer Machine boasts the core advantages of dual-purpose functionality and adaptability to multiple operating conditions, supporting both upward blind shaft construction and reverse shaft construction—the two key processes. Its overall construction capability far surpasses that of comparable small-scale raise boring equipment. When performing blind shaft operations, the machine can stably handle deep shafts with a diameter of 600 mm and a maximum depth of 60 m; upon switching to reverse shaft mode, it can execute reverse shaft drilling with a diameter of 1.2 m and a maximum depth of 120 m. It comprehensively meets the construction needs of conventional underground shafts such as mining cut-off shafts, ventilation shafts, and chutes, demonstrating exceptional versatility and practicality.
Meanwhile, the equipment is equipped with automated robotic arms and a boom, enabling fully automated operations throughout the entire process. Construction efficiency remains consistently at 30–45 minutes per meter, with borehole deviation accurately controlled within 0.5%. The wellbore walls are smooth and well‑formed, and disturbance to the surrounding rock is minimal, effectively mitigating issues associated with conventional blast‑driven tunneling and manual shaft sinking—such as rock damage, poor borehole accuracy, and numerous safety hazards.

Tackling harsh high-altitude working conditions and overcoming challenges in accessing the construction site.
Since the equipment was delivered to Xinzhou Mining, Yier Technology has consistently adhered to the service philosophy of “equipment delivery plus end-to-end support,” providing customers with comprehensive, full‑cycle, dedicated after-sales service guarantees. To ensure the smooth progress of the project and the efficient, stable operation of the equipment, the company specially dispatched senior after-sales engineers Chen Miao and Fu Jie to be stationed on site for continuous oversight. During their on-site tenure, the two engineers remained firmly rooted at the construction front line, completing in advance all preparatory tasks, such as equipment commissioning upon arrival and the layout of underground chambers.
The mining area for this operation is located at high altitude, with an elevation range of 2,520 m to 4,500 m. The access road is a steep, winding gravel track characterized by potholes and a loose subgrade, posing significant challenges to the transportation and deployment of equipment up the mountain.

Faced with numerous operational challenges, our company’s after-sales team adhered rigorously to the service principles of safety first and professional accountability, conducting a comprehensive, expert assessment across three key dimensions: equipment performance parameters, on‑the‑ground road conditions in mountainous terrain, and mine‑site safety regulations. Despite the physical discomfort caused by altitude sickness, our technicians remained steadfast at the front lines, fulfilling their duties with dedication. Drawing on the specific operating conditions of the mining site, they devised a tailored, scientifically sound and robust plan for optimizing equipment relocation, successfully completing the entire transfer process from the delivery point to the construction location. Throughout the operation, they simultaneously and precisely collected real‑time field data, providing a solid and reliable technical foundation for subsequent secondary safe relocations and compliant, standardized construction, effectively mitigating various safety risks and ensuring the project’s steady, orderly progress. The team’s professional, pragmatic, and responsible service was highly commended by the client.

Professional on-site operations and maintenance, with all‑round support to ensure smooth project implementation.
During construction, the two team members closely monitored equipment performance in real time, conducted routine inspections, performed preventive maintenance, and systematically identified potential hazards. They promptly addressed on-site operators’ questions about equipment use, providing hands-on guidance on proper operating procedures, daily maintenance, and troubleshooting common issues. By offering comprehensive support across equipment commissioning, construction oversight, technical guidance, and operational assurance, they ensured the smooth and safe execution of the project.
With the professional support of after-sales personnel and the robust performance of the equipment, this 30-meter cutting‑well operation was completed efficiently, significantly shortening the project’s construction timeline, reducing underground operational safety risks, and delivering substantial cost savings for Xinzhou Mining. As a result, it has earned high praise from both the mine site’s project manager and the frontline construction team.

This project has concluded successfully, serving as strong evidence of the robust capabilities of Yier Technology’s ATM-600T compact cutting Raise borer Machine, and also fully demonstrating the company’s high-quality after-sales service system.
In the future, Yier Technology will continue to deepen its expertise in underground drilling equipment for mines, constantly optimizing equipment performance and iterating product technologies, while continuously improving its end-to-end after-sales service system. With higher-quality equipment, more professional technology, and more attentive service, it will empower major mining enterprises to achieve efficient, safe, and environmentally friendly underground operations, thereby supporting the intelligent and efficient transformation and upgrading of the mining industry.
