Description

technical field

[0001] The invention relates to the technical field of radiochemical analysis, in particular to a method for detecting the position of a coal spontaneous combustion fire source by using the polonium-210 method. Background technique

[0002] The coal industry is an important basic industry related to the lifeline of the national economy, and has a long-term, stable and irreplaceable basic position in the national economy. 56% of the mines in my country mine combustible coal seams. According to data, more than 70% of the mines in my country have spontaneous combustion fire areas or areas with spontaneous combustion fire hazards. Fires caused by coal spontaneous combustion account for more than 90% of the total number of mine fires. Coal mine gas and coal dust explosions caused by natural fires occur from time to time. At the same time, the harmful gases released by coal spontaneous combustion will seriously affect the regional ecological environment and direct...
