Research status and trend of hydrogen sulfide control technology in coal mine

When mining the coal seam with hydrogen sulfide, there is a risk of hydrogen sulfide accident, which threatens the safety of miners and corrodes underground machinery and equipment. This paper expounds the harm of hydrogen sulfide in coal mines, analyzes the causes and sources of hydrogen sulfide in coal mines, probes into the research status of hydrogen sulfide prevention and control technology at home and abroad, sums up the common methods of hydrogen sulfide treatment on site, discusses the main technologies of hydrogen sulfide prevention and control in coal mines respectively, and points out that there are still some deficiencies in hydrogen sulfide prevention and control in coal mines, such as incomplete and effective hydrogen sulfide treatment The results are not ideal; the absorption solution can not be fully utilized, resulting in waste of raw materials; the degree of automation is not high, and it is difficult to achieve rapid intelligent monitoring and multi regional joint governance. It is proposed that the prevention and control technology of hydrogen sulfide in coal mines need to further strengthen the theoretical basis research, build a hydrogen sulfide classification early warning system and an intelligent monitoring early warning system, comprehensively control the original coal seams, working faces, goafs and other multiple sources, develop new prevention and control technology of hydrogen sulfide in multi regional coal mines, and constantly research and innovate, so as to make hydrogen sulfide treatment more efficient and economic.
