Gas microchromatograph for detection of gas and/or fire hazard in mining
The paper presents fire and gas hazards occurring in underground hard coal mines; methods of hazard detection and methods of gas concentration measurement used while monitoring and/or mine rescue operations. Chromatographs applied to measurement of atmosphere in mine underground and construction of the own-design gas chromatograph; functional examination of the microchromatograph and analyses of gas mixtures are discussed.
