New Method for Ventilation Methane Content Monitoring

In this article, the results of experiment measurements were presented. Methane content was measured using newly designed, innovative measuring instruments. The devices make measurements simultaneously and quasi-point. The instruments are prepared to measure methane concentration and air velocity in deep coal mines. The article describes both the handheld and stationary instruments. The method of making measurements and using the measuring instruments was discussed and explained. Measurements were made in a region of a longwall ventilated by means of a U-type ventilation system in normal excavation conditions. The gathered data were compared with the standard acquisition data from the sensors of the mine’s telemetry system.
