Mine safety and explosion protection are important elements in the realisation of projects within the underground coal mining industry. The demands on ventilation systems for underground workplaces are high. Special measures are required to cope with the presence of firedamp resulting from the extraction of coal or from microbial processes. The main component of firedamp is methane gas (CH4) which is highly explosive in certain concentrations.
At low levels of gas, it is sufficient to dilute the concentration of methane by means of an increased supply of fresh air to avoid the risk of explosion and to ensure mine safety. At higher levels of gas, it is necessary to drain the methane. The installation of a methane drainage system or a combination of procedures is recommended.
We offer innovative solutions for methane drainage in cooperation with our partner Brockhaus Lennetal GmbH. At the heart of our offering are drainage systems with rotary piston compressors and systems with liquid ring vacuum pumps. We engineer the necessary pipework together with our partner. The resulting solutions contribute to enhanced mine safety and increased productivity. These systems can be installed in disused mine workings to extract considerable volumes of methane gas which can then be utilised - for example in a gas-fired combined heat and power plant.
