ch detectors for coal mines

ch detectors for coal mines

Early detection of spontaneous explosions in coal mines can be made possible by monitoring the concentration of toxic gases such as Carbon monoxide (CO), Methane (CH 4) and Hydrogen sulfide (H 2S). Methane gas detection is very important for outburst prediction.
