Integrated system for monitoring and analysis of methane hazards in the longwall area
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2016, Vol 525, Issue 1
Abstract
Polish hard coal mines with high methane explosion hazards commonly use systems for automatic monitoring of air parameters. These systems are used by ventilation personnel in preventive actions, simulation tests and designs. The systems work independently and the measurement data, needed for ventilation calculations, are used only off-line and in a small extent. As a result of that, the calculations are conducted on obsolete data and their results are often far from reality. The European project AVENTO dealt with the integration of systems that enable to supply measurement data to calculation programs working in real time mode. The integration enables to observe on-line the changes in ventilation parameters and the level of methane explosion hazard. In addition, it allows to calculate the hazard indicators stipulated by valid regulations, along with the balance of methane which is drained along ventilation paths and pipelines of the degassing system. The paper reports also result of in situ tests of the integrated system.
