Requirements for the development of an effective autonomous methane detection system protecting against a sudden emission of methane
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2015, Vol 521, Issue 1
Abstract
The paper features the development origin of a new methane measuring system whose main purpose is to provide quick protection of heavily saturated methane longwalls against a sudden emission of methane from goafs into the working area of the longwall. The concept of the new system was discussed along with its testing results. This work was the subject of task 8 of the project devoted to improving safety in mines. The focus was put on implementation conditions: from obtaining indispensable certificates and admissions, through the installation in the given exploitation area, to the system integration with already existing stationary gas measuring systems. The possibilities of the new system were stressed as far as the safety management of the mine was concerned. Here, the authors pointed at the significance of systematic risk analyses with respect to methane explosions in longwall areas.
