Recently, the optical fiber composite power cable for coal mines developed by SXYG Cable Technology Group has successfully obtained the national safety mark certificate for mining products, indicating that the company has the qualification to independently and legally produce this product. At present, only three cable companies in the country can produce such products.
At present, digital signal transmission and electric energy transmission cables in coal mine roadways are basically laid in different categories. Various cables have increased the cost of coal mine expenses and increased labor intensity. In addition, due to the thinner optical cables, the tensile and compressive strengths are poor, so they are used in underground production environments. It is easy to cause the signal to be interrupted due to damage to the optical cable caused by pulling or external forces. The optical fiber composite power cable for coal mine is a combination of optical fiber and cable, which can simultaneously solve the problems of equipment power consumption and digital signal transmission. It has the advantages of fast installation, anti-electromagnetic interference, and high safety. It is also conducive to standardized management of mine safety and quality.
Long-distance automatic control mining and unattended working face of coal mines have always been the goals pursued by the coal mining industry. Optical fiber sensors are more and more widely used in coal mines, and the requirements for mining cables and optical cable products are becoming higher and more integrated. At the same time, with the development of optical fiber monitoring technology, this type of product can realize online temperature and vibration monitoring to ensure the safety of coal mine electricity. With the construction of 5G+ smart mines, the promotion and application of optoelectronic composite cable technology in coal mines will become the mainstream trend in the future, helping the construction of smart mines.
