Problems solved by technology

[0002] Coal has always been an important energy source in the world. 70% of my country's power resources also come from coal combustion. In order to ensure the continuous supply of raw coal, the normal operation of coal mine mining systems, conveying systems, ventilation systems, and drainage systems, mining cables The quality of the cable is very important. The environment for mining cables is harsh, the geological structure is complex, and it is flammable and explosive, and often needs to be pulled and moved. Due to poor mechanical properties and flame retardancy, the sheath is easily damaged or even broken. Unable to meet the normal power supply needs of the mine
