What Is The Standards for Mine Lighting?

Mar. 20, 2019

Countries with a well-established underground mining business are often quite specific in their requirements regarding what constitutes a safe Lighting Lamp For Mining. This is particular true for mines that have methane gas given of from the working, typically coal mines.

Mining Lighting Lamp

Methane gas can ignite and cause an underground explosion with devastating results. Consequently any lights must be designed to be either “intrinsically safe” or “explosion proof”. An intrinsically safe light source is one in which the current feeding the light has very little energy so that any short in the circuit would not produce a spark which could ignite the methane gas. For a Mining Lighting Lamp to be explosion proof, any explosion triggered by the lamp’s electrical activity is contained within the device. In addition, the device itself will not become hot enough to cause an explosion. The lamp is more expensive, heavier, with metal parts usually made of castings. Governments usually have test facilities to certify whether lamps can be classified for use in a gassy mine. A low-pressure sodium lamp could not be so certified as the sodium in the lamp could ignite if the lamp were to break and the sodium came in contact with water.
