• Advancements in Self-Rescue Devices:

The evolution of self-rescue devices has been one of the most impactful advancements in mining safety, and Zhejiang Zheng'an Explosion-Proof Electrical Co., Ltd. has played a pivotal role in driving this innovation. Traditional self-rescuers often suffered from limited duration, heavy weight, and complex operation—issues that could prove fatal in high-pressure scenarios. Zheng'an addressed these challenges by introducing lightweight, ergonomic designs such as the ZYX45 compressed oxygen self-rescuer, which weighs less than 2.5 kg yet provides a full 45 minutes of breathable oxygen. The device features a built-in pressure gauge and audible alarm that triggers at low oxygen levels, enabling users to monitor their remaining time without removing the mask. More impressively, the company pioneered the integration of modular components: the ZYX series units can be paired with optional backup batteries and external CO2 absorbent cartridges, extending operational time in prolonged emergencies. In 2021, a trial conducted by the National Coal Mine Safety Institute tested Zheng'an’s ZYX45 against five other brands under simulated mine fire conditions. The results showed that Zheng'an’s model maintained stable oxygen output for 48 minutes—exceeding its rated time—while others failed after 38–42 minutes due to thermal degradation. This resilience stems from Zheng'an’s use of high-grade ceramic filters and heat-resistant seals developed through collaboration with Zhejiang University’s Materials Science Department. Additionally, the company introduced a smart version of the ZYX45 equipped with a Bluetooth-enabled sensor that transmits real-time data to a central command hub, allowing rescue teams to track the location and status of each miner remotely. Such innovations are now being adopted in new mine construction projects across Xinjiang and Guizhou, marking a shift from passive protection to proactive, data-driven safety management.

• Importance of Gas Detection Instruments:

Gas detection instruments are the frontline defense against catastrophic accidents in underground mines, and Zhejiang Zheng'an Explosion-Proof Electrical Co., Ltd. has redefined their capabilities through cutting-edge sensor technology and intelligent integration. Their CJG10(x) miniature optical interference methane detector, for instance, combines precision optics with rechargeable lithium-ion batteries, offering a detection accuracy of ±0.1% CH4 and a battery life of up to 12 hours—ideal for extended shifts. What sets it apart is its ability to operate in extreme humidity and dust-laden environments, thanks to a patented sealed lens system that prevents contamination. In a landmark incident in 2019, a coal mine in Hebei experienced a slow methane accumulation over several days. Without early warning systems, the situation could have led to a major explosion. However, Zheng'an’s Methane-Oxygen Dual-Parameter Alarms, deployed throughout the ventilation shafts, detected rising methane levels (from 0.8% to 1.5%) and falling oxygen levels (from 20.5% to 17.2%) simultaneously, triggering an automatic shutdown of machinery and evacuation protocols. This early intervention prevented disaster and was later cited in a government safety review as a model for preventive monitoring. Beyond standalone devices, Zheng'an has developed networked gas monitoring systems that link multiple sensors via intrinsically safe communication networks, enabling real-time data aggregation on a centralized dashboard. These systems are now standard in over 30 large-scale mines across China. The company’s ongoing R&D, including AI-powered anomaly detection algorithms developed with Hangzhou Institute of Technology, allows for predictive alerts based on historical trends—transforming gas detection from reactive to predictive. By combining ruggedized hardware with intelligent software, Zheng'an ensures that no gas threat goes unnoticed, making it a cornerstone of modern mine safety infrastructure.
