Výzkum a využití indikačních plynů samovznícení uhlí v Číně

Ing. Xyiang Feng, prof. Ing. Alois Adamus, Ph.D.

Čína je v současné době globálně nejvýznamnějším těžařem uhlí s převahou hlubinného dobývání. Četné doly zde těží sloje náchylné k samovznícení, které jsou zdrojem rizika endogenních požárů. Počátky výzkumu a aplikace indikačních plynů samovznícení uhlí pochází v Číně z 60. let minulého století. Ke značnému rozvoji došlo v 90. letech, kdy byl dokončen státní výzkumný program "Charakteristika adsorpce kyslíku uhlí a její aplikace v prevenci důlních požárů". Článek stručně popisuje přehled historického vývoje aplikace indikačních plynů samovznícení uhlí v Číně, dosažené výsledky výzkumu, technické vybavení, související čínskou legislativu a normalizaci.

Klíčová slova: uhlí, samovznícení, indikační plyny, vyšší uhlovodíky

Research and application of indicator gases of coal spontaneous combustion in China

China is currently the most important producer of coal globally with a predominance of underground mining. Numerous mines here benefits the seam prone to spontaneous combustion, which are a source of risk of endogenous fires. The beginnings of the research and application of indicator gases in coal spontaneous combustion in China comes from the sixties of the last century. The further significant development occurred in the 1990s, when the national research programme "Characterization of the oxygen adsorption of coal and its application in the prevention of mine fires" was completed. The article briefly describes an overview of the historical development of applications of spontaneous combustion of coal gas indicator in China, research results and technical equipment related to the Chinese legislation and standardisation.

Keywords: coal, self-ignition, indicator gases, higher hydrocarbons
