Provide security for mining work: the appropriate choice and use of mining cables

In recent years, with the development of the mining industry and technological advances, people have been paying more attention to mine safety.




Particularly in the mining industry, safety is the primary consideration. In order to ensure the safety of mining production, we need to choose the right mining cable and use it correctly.

In this article, we will introduce the selection principles of mining cables in detail, in order to improve the level of mine safety.

Firstly, in vertical shafts or shafts with an inclination angle of 45° or above, one should use vinyl chloride insulated thick steel wire armoured PVC sheathed power cables or cross-linked polyethylene insulated thick steel wire armoured PVC sheathed mining power cables.

These cables have relatively high mechanical strength and high temperature resistance, and can withstand the complicated mining environment to ensure the stable transmission of power.

Secondly, in the horizontal tunnel or in the inclination angle of 45 ° below the shaft, should be used in PVC insulated steel tape or fine steel wire armoured PVC sheathed power cables.


Cross-linked vinyl steel tape or steel wire armoured PVC sheathed mining power cables. These power cables have good moisture-proof and erosion-proof performance and are suitable for use in mines.

One may use aluminium-core cables in the inclined shafts for air intake, in the yards at the bottom of the shafts and in the vicinity of these locations, and between the central substation and the mining substation, but copper-core cables must be used in all other locations.

Copper-core cables have greater electrical conductivity and thermal stability, which reduces power losses and improves mine productivity.

Need to be fixed for the laying of low-voltage mining cable line, should be used Mw armoured or non-armoured corresponding to the voltage level of the mobile rubber-coated flexible cable.

These cables have good bending properties, convenient in the mine for fixed laying.

High and low voltage cables that are not laid in a fixed situation must be rubber sleeved flexible cables in accordance with Mr818.

Mobile and hand-held electrical equipment should use specialised mine rubber cables.

Cables for lighting, communication, signalling and control purposes should be armoured communication cables, mine rubber cables or mine M plastic power cables.
