An acetylene gas miner s lamp carbide lamps or acetylene gas lamps are simple lamps that produce and burn acetylene c 2 h 2 which is created by the reaction of calcium carbide cac 2 with water h 2 o.
In the late nineteenth century lamp makers began to develop dedicated gas testing lamps such as the clowes hydrogen lamp that would give more sensitive readings of methane levels.
Acetylene gas was originally discovered by edmund davy in 1836 but commercial production of calcium carbide only became feasible due to the efforts of thomas wilson in 1894.
This reaction produces acetylene gas c 2 h 2 which burns a clean white flame.
This workhorse operates for 18 hours at 7000 12000 lux before it needs to be recharged and the durable battery offers over 1000 cycles before needing to be replaced.
The electric cap lamp these lamps had to be an intrinsically safe design applied to electrical equipment and wiring specifically for hazardous locations such as coal mines.
Both of which became very dangerous because of hidden gasses.
Their headgear consisted of cloth or canvas hats with leather brims as well as metal lamp brackets on the front to hang their source of light.
The oil wick cap lamp issued a bare flame giving off enough light for miners to see what was in front of their face but not much further.
The technique is based on limiting energy either electrical or thermal to a level below that required to ignite a specific hazardous atmospheric mixture.
First national battery miner s cap lamps have been designed for harsh underground mining conditions and are used by all the major south african mining groups which mine platinum gold diamonds coal uranium copper iron and antimony.
Soon after the introduction of the safety lamp underground miners noticed that its flame changed if there were gases in the atmosphere.
