Abstract

The invention discloses a device for treating hydrogen sulfide gas on an underground coal roadway driving working surface through a gas atomization alkaline fluid, and belongs to the field of mine safety production. The device is suitable for treating associated harmful gas in a mine production process, and is characterized in that the device is simple in structure and convenient to operate, the main purpose of safe production in the tunneling process is achieved, the treatment problem that hydrogen sulfide gas escapes continuously under the original stress change condition is solved, the treatment effect is obvious, the efficiency is high, both manifestation and cost are controlled, the effect of protecting safe production of mines is achieved, and the treatment problem of hydrogen sulfide escape is fundamentally solved. According to the invention, hydrogen sulfide associated treatment becomes an event which can be easily realized in daily work and life.

Description

technical field [0001] The invention relates to a device for treating hydrogen sulfide gas at the driving face of an underground coal roadway with a gas atomized alkaline fluid, which belongs to the field of mine safety production and is suitable for the treatment of harmful gases associated in the mine production process. Background technique [0002] The main reason for the abnormal gushing of underground H2S is that there is an abnormally enriched area of ​​H2S in the coal seam, which is affected by the mining of the coal seam, resulting in the change of mine pressure, and then the sudden release of H2S gas from the broken coal body. However, because H2S gas has not occurred in most coal mines at present, or the occurrence is very low, even if H2S gas appears during the mining process, due to the low concentration, no accidents have been caused. The content of research on prevention and treatment is relatively small. In some areas of my country's mining areas, the H2S co...
