Research On Hydrogen Sulfide Content Test Device And Test Method Of Coal Seam

Hydrogen sulfide as one of the poisonous and harmful gas in the mine, in recent years, with the enlargement of the mining areas and the increase of mining depth, hydrogen sulfide poisoning casualties have multiple occurrences of workers, so to understand and grasp the status and content of hydrogen sulfide in coal seam, to prevent hydrogen sulfide poisoning accidents has important significance.Based on the analysis comparison test device, gas content in combination with hydrogen sulfide characteristics, design and research of hydrogen sulphide content test equipment, including downhole desorbing, ground desorbing, vacuum degassing device, etc. As well as develop hydrogen sulphide at various stages of testing methods, and the data processing method.Compared by sampling in the mine site, by testing the content of hydrogen sulfide of device and the method of validation results. The experimental results show that the device can detect H2 S content in coal seam, through the measured coal content of hydrogen sulfide and the coal industrial analysis parameters, and coal seam gas of each parameter and by different coal sample hydrogen sulfide adsorption experiments that the results credible. And the hydrogen sulfide concentration data measured by the hydrogen sulfide sensor in the air of the air flow is analyzed, and the results are also further explained.This device and testing methods of research for hydrogen sulfide mine coal mining deployment, spread design, hydrogen sulphide occurrence regularity of coal seam, prognosis of the volume of hydrogen sulfide, hydrogen sulfide, coal working face and the abnormal regional assessment and prediction, drainage effect of hydrogen sulfide in coal mine has important guiding significance to the prevention and control of hydrogen sulfide, etc.
