Fire Prevention in Underground Mining – Requirements for Equipment in Germany and Europe
Fires have been one of the major hazards for miners. In order to minimize fire risks in underground mines, preventive measures need to be taken. Such means are for example using materials which are hard to ignite and hardly spread fire or hydraulic fluids with low flammability. Testing and assessing…

Hazard Analysis on Underground Mine Fires in Collieries
Since the mid sixties, there were over 200 spontaneous combustion fires in German collieries, with more than a dozen cases of CH4 ignitions. It should be agreeable that the related mine rescue work for the prevention of damage to property should not be more hazardous than ordinary underground work. This…

Early Detection of Smouldering Fire Using the GESO-FireFinder M-System – Description and Experiences
The arising of smouldering fire of slack coal in close proximity of conveyer belt systems still cannot be prevented despite of all safety engineering. That is why it is necessary to find the source of fire at an elementary stage and detect it locally. The GESO Firefinder M is based on…

One Seven MINING – an Innovative System for Firefighting and Prevention in Mining
By adding a special foam concentrate and compressed air to water the One Seven MINING system produces compressed air foam (CAF). The foaming agent is a surfactant and a non-flammable substance unlike phenol or polyurethane. By inundating a mine space with foam it displaces any explosive gases and prevents oxygen…

Latest Developments in LIBS for Distinction of Coal and Waste Rock in Explosive Areas
The Institute for Mineral Resources Machine Technology (IMR) at the RWTH Aachen University, Aachen/Germany has been working on options to enable boundary layer detection as well as horizon control for underground coal operations for more than a decade. One of these tested options is laser-induced breakdown spectroscopy (LIBS). After a…
