Zaozhuang Mining Fuchun Coal Industry, as a backbone mine in East China, faces complex explosion risks such as gas and coal dust during underground operations. Jindun Electric relies on the technological accumulation in the mining explosion-proof field to build highly reliable explosion-proof electrical systems for key areas such as mining workfaces and transportation tunnels.
Customized Ex d I Mb mining explosion-proof frequency converter and motor for coal and gas outburst areas. The shell is made of impact resistant ductile iron forging, combined with multiple mechanical locking designs, with a protection level of IP68. The project deployed 32 explosion-proof combination switches and 86 sets of intrinsic safety sensors, equipped with AI intelligent linkage control modules, to monitor gas concentration and equipment insulation status in real time. The response time for abnormal power outages was shortened to 0.05 seconds. The original air-cooled explosion-proof LED lighting system maintains stable operation for 6000 hours in environments with dust concentration>1000mg/m ³.
The engineering team synchronously implements the EMC three-level shielding scheme for explosion-proof equipment to ensure zero interference in underground communication systems. After the renovation, the explosion-proof compliance rate of underground substations reached 100%, the equipment failure rate decreased by 60%, and the annual maintenance cost was saved by more than 2 million yuan, laying a solid safety foundation for the intelligent construction of coal mines. Jindun will continue to use cutting-edge explosion-proof technology to assist in the safe and efficient development of the mining industry.
