METHODS AND MEANS OF COMBA TING HYDROGEN SULFUR IN MINERAL AIR AND UNDERGROUND WATER
Hydrogen sulfide is one of the most toxic gases found in nature. It is contained in natural combustible gases, in volcanic emissions, in deep little-flowing lakes and seas, in underground waters of sulfate-carbonate formations, and even in salt deposits. Hydrogen sulfide is especially dangerous in mines. The data on the properties of hydrogen sulfide are given, since they are the basis for the development of methods and means of combating it. Methods and means of combating hydrogen sulfide in mine air and groundwater are also described. Normalization of sanitary and hygienic working conditions of miners in dead-end combine workings with intensive release of hydrogen sulfide and high dust formation can be ensured by using "wet" and "dry" type gas neutralizers installed in the face space of workings.
