Monitoring plynů při likvidaci důlních požárů

Abstract

The bachelor diploma work is focused on the issues of the monitoring mine gases during fighting of mine fires. There is a description of a development of fire gases in the mines and their monitoring. The work is focused on essential technical means of monitoring and describes the personal detectors, stationary analyzers, sophisticated gas chromatography technology and a gas mining laboratory. Another part deals with the specifics of endogenous fire gases and spontaneous combustion of coal. There is also described the most common method of estimating temperature of spontaneous combustion according to the methodology of the HBZS and CnHm computer program. The description of the details of the fire gases explosion follows. The work contents a description of conditions and the effects of an explosion and a possible solution of calculations of an explosion of fire gases by using graphic models or a computer program “Explosion triangle”. Finally, the author presents his experience on the use of the mine gas laboratory and suggests the possibility of innovation.
