On December 1, 2025, the national standard "GB/T 12761-2025 Raise borer Machine," jointly developed by Hunan Yier Mining Technology Co.，Ltd., officially came into effect and is now in force.

As the core technical standard in the field of Raise borer Machine, this standard replaces the 2010 edition and fully aligns with the industry’s trends toward intelligent and green development. It will provide a brand-new, unified set of guidelines for the design, manufacturing, inspection, and application of Raise borer Machines in China’s underground mines and underground engineering projects, thereby propelling the industry into a new stage of high-quality development.

The Raise borer Machine is the core equipment for constructing critical shafts such as ventilation shafts, filling shafts, and chute shafts in underground mines. Its technological level and safety performance directly affect mining efficiency and operational safety.

As China's mineral resource development extends deeper underground and the scale of underground engineering construction continues to expand, the market is placing higher demands on the intelligent level, environmental adaptability, and safety protection capabilities of Raise borer Machines. The existing 2010 edition of the standard can no longer adequately cover new types of equipment such as remotely operated drill rigs and crawler-mounted drill rigs, nor can it meet the safety and environmental protection regulations of the new era. Therefore, revising the standard has become imperative.

As one of the core participating units in the development of this national standard, Hunan Yier Mining Technology Co.，Ltd. has deeply engaged in the entire process—research, drafting, and validation—of the standard, leveraging its many years of technical expertise and practical experience in the field of Raise borer Machine. Drawing on its hands-on experience in the R&D, production, and on-site application of mining equipment, the company has put forward numerous constructive suggestions on key aspects of the standard, including machine classification, technical parameters, safety requirements, and testing methods. Some of these suggestions have been incorporated into the core provisions of the standard, providing crucial support for its scientific rigor, practicality, and forward-looking nature.

Compared to the 2010 edition of the standard, "GB/T 12761-2025 Raise borer Machine" has achieved significant breakthroughs in multiple aspects. In terms of scope of application, new models such as remote-controlled drill rigs, crawler-mounted drill rigs, and tire-self-propelled drill rigs have been added, comprehensively covering the current mainstream equipment types in the industry.

In terms of safety requirements, the number of safety control clauses has been increased from 12 to 17, with new key requirements added, including fire extinguisher configuration, warning signs, and diesel engine exhaust emissions. Specifically, the regulations clearly stipulate that for diesel-engine-driven drilling rigs, the nitrogen oxide emission limit shall be ≤900×10⁻⁶ and the carbon monoxide emission limit shall be ≤1500×10⁻⁶, further strengthening the equipment’s safety and environmental protection attributes.

In terms of testing methods, nine new test items have been added, including average ground pressure of tracks, climbing ability, braking performance, and noise detection, providing a more comprehensive technical basis for equipment quality inspection.

It is understood that this standard was proposed by the China National Machinery Industry Federation, under the jurisdiction of the National Technical Committee for Standardization of Mining Machinery. It was jointly drafted and completed by several research institutions and leading enterprises, including the Changsha Institute of Mining Research and XCMG Energy Equipment. The implementation of this standard will effectively regulate the market order for Raise borer Machines, address issues such as uneven product quality and inconsistent technical specifications within the industry, provide enterprises with clear technical benchmarks for production, and also serve as an authoritative basis for law enforcement by regulatory authorities.

For downstream users, the standardization will reduce the risks associated with equipment selection and usage, ensuring construction safety and efficiency. For the industry's development, it will guide enterprises to focus on R&D of intelligent and green technologies, thereby promoting the transformation and upgrading of China's Raise borer Machine industry from "manufacturing" to "intelligent manufacturing."

In the future, Yier Technology will take the entry into force of this standard as an opportunity to strictly optimize product design and production processes in accordance with the new standard requirements. We will continue to increase R&D investment in areas such as intelligent control and green energy efficiency, and launch more high-end Raise borer Machine products that meet the standards and satisfy market demands.
