1. What’s Coal mining cables?

Mining cables are essential wires and cables used in the mining industry, especially critical in coal mines. They are applied to connect coal mining machines, conveyors, basic lighting systems, communication equipment and other devices. Due to the harsh underground environment and the risk of explosion caused by accumulated coal dust, mining cables (including coal mining cables) must meet extremely high safety standards.

2. Requirements for Chinese Mining Cables

Special cables for coal mining uses are the general term for coal mine cables. All mining cables are insulated wires and must obtain the Safety Certificate for Mining Products issued by the China Safety Certification Center for Mining Products (MA). Mining cables refer to wires and cables used in surface and underground equipment for coal mining, including cables for coal shearers, conveyors, communication, lighting and signal devices, as well as cables for electric drills, cap lamp wires, and power cables for underground mobile substations.

Taitong coal mining cables are manufactured in accordance with GB/T 12972-2008 Rubber-sheathed flexible cables for mines and MT 818-2009 Flame-retardant cables for coal mines. We can also produce special cables for coal minging use according to customers’ requirements, following international standards such as IEC, BS (British Standard), VDE (German Standard) and UL (American Standard).

3. Service life

Taitong provides a wide range of mining cable models, including mining power cables, mining control cables, shearer cables, and mobile rubber-sheathed flexible mining cables. Different types have different service lives.

Mining power cables and mining control cables are usually for fixed installation, with a long service life of at least 10 years.

Shearer cables have a shorter life: high-quality ones last 6 months to 1 year, while inferior ones only 7 days to 3 months. For safety reasons, coal mines replace them regularly.Mobile flexible mining cables generally last more than 1 year.

Special cables for coal mining uses are short for coal mine cables, and all mining cables are flame-retardant cables.
