China Coal Research Institute Mine Individual Equipment Intelligent Technology Team has addressed long-standing weaknesses in occupational health protection and the low level of intelligence in individual equipment within China's mining industry. With the core objective of enhancing miners' safety and work efficiency, the team successfully developed China's first integrated solution for coal miners' occupational health protection and intelligent wearable needs through systematic technological innovation and interdisciplinary collaboration. These achievements target key challenges in mining environments, such as high dust concentration, hazardous gas accumulation, complex terrain limitations, and inefficient human-machine interaction. They establish a comprehensive technological system covering respiratory protection, environmental perception, intelligent interaction, and emergency support, marking a leap in China's mine safety equipment from traditional passive protection to active intelligent protection. In the field of occupational health protection, the team broke through the limitations of traditional protective equipment, such as single functionality and poor comfort. They innovatively proposed a technical path of "active defense + dynamic purification." The self-developed mine individual positive pressure protection system utilizes aerodynamic simulation and ergonomic optimization to create a multi-level protection mechanism combining graded filtration and intelligent airflow regulation. While ensuring high-efficiency respiratory protection, it significantly improves wearing comfort over long periods through substantial optimization based on respiratory flow field simulation. At the level of intelligent perception and interaction technology, the team established a distributed intelligent individual equipment system architecture. Through an edge computing and cloud collaboration approach, they achieved modular expansion and self-adaptive networking capabilities for the equipment system. The core device, the intelligent helmet, integrates a miniature environmental monitoring array that can detect real-time concentrations of key gases like methane, carbon monoxide, and oxygen in the work area. Combined with environmental parameters such as temperature, humidity, and air pressure, it builds a multi-dimensional safety assessment model. When abnormal data is detected, it automatically triggers audible and visual alarms and initiates emergency protection protocols. The innovatively developed augmented reality display system overcomes the limitations of complex underground lighting environments by using low-power micro-projection technology and an optical waveguide display solution, superimposing key data such as geological structure information, equipment operational status, and escape route guidance onto the real field of view as holographic images. The bidirectional bone conduction audio system, through deep optimization of vibration sensors and noise cancellation algorithms, maintains clear voice communication even in high-noise underground environments. By deeply integrating Internet of Things (IoT) and artificial intelligence (AI) technologies, the team developed a Mine Underground Personnel Networking System platform. Using a heterogeneous data fusion engine, it enables real-time parsing and intelligent linkage of diverse information including personnel positioning, vital signs, environmental parameters, and equipment status. Through distributed positioning algorithms combining inertial navigation and ultra-wideband (UWB) technology, coupled with 3D digital twin maps, it enables dynamic path planning and risk early warning. The vital signs monitoring module uses flexible e-textile technology to continuously collect physiological data such as ECG, body temperature, and motion status. Machine learning models establish individual health baselines for early warning of occupational health risks like fatigue state and heat stress response. The equipment also innovatively integrates device interaction control functions, enabling intelligent interconnection with large equipment like shearers and roadheaders through near-field wireless communication protocols. This allows operators to monitor equipment status and perform key operations from a safe distance, significantly reducing the risks associated with close-range work. The promotion and application of these technological achievements fundamentally transform the traditional passive defense mode of mine safety protection equipment, establishing a closed-loop protection system of "intelligent perception - active protection - collaborative decision-making - dynamic optimization." Verified through underground industrial trials, the system can effectively protect against occupational health risks caused by high-dust environments, significantly improve emergency response efficiency for sudden incidents, and markedly enhance operational efficiency in complex working conditions. It provides crucial equipment support for the digital transformation of the mining industry. The technological breakthroughs are manifested not only in hardware innovations but also in building a complete technological ecosystem covering equipment R&D, data middleware, and intelligent algorithms, forming a replicable and promotable standard system for intelligent individual equipment technology. The industrialization of this R&D achievement will powerfully propel China's mine safety equipment from following to running neck-and-neck, and then to leading the way. It provides a technological paradigm for practicing the "people-oriented" safety development concept, holds milestone significance for promoting the intelligent transformation and upgrading of the mining industry and building a new mine safety assurance system, marks that China has reached internationally leading levels in the field of mine intelligent wearable equipment, and contributes Chinese solutions to the development of global mine safety protection technology.
