AI Technical Summary

Technical Problem

The existing coal mine power cables are insufficient in extreme conditions, especially in fire situations, which makes it difficult to supply power continuously, making emergency rescue work difficult, and the combustion of conventional fire-resistant cables produces toxic smoke, threatening the safety of miners.

Method used

A solid fire-resistant power cable for coal mines was designed, using a multi-layer fire-resistant protective layer and a built-in special temperature-sensitive optical cable, combining intelligent cable early warning host, management software and visual interface to realize real-time temperature and orientation data acquisition and intelligent alarm.

Benefits of technology

Continuously and stably power supply to the equipment under medium-sized fire conditions, improve emergency rescue efficiency, reduce casualties and property losses, and avoid secondary pollution.
