Genesis, controls and risk prediction of H2S in coal mine gas
The Chinese "Coal Mine Safety Regulations" states that the H 2 S concentration of coal mine gas is considered abnormal if it concentration is greater than 6.6 ppm 1, 2, 3. Such concentrationsThe venting of methane from coal mining is China’s main source of methane emissions. Accurate and up-to-date methane emission factors for coal mines are significant for reporting and controlling methane emissions in China. This study takes a typical coal mine in Shanxi Province as the research object and divides the coal mine Atmosphere Free Full-Text Study on Characteristics and

Characteristics of Water Hazards in China’s Coal Mines: A
China’s coal mines face very complicated hydrogeological conditions and are affected by many complex water hazards. Based on the condition of the coal seams and an analysis of regional hydrogeological and geological conditions, China's coal-producing regions have been divided into six major hazard regions. This paper summarizes the An ongoing resurgence of occupational lung disease among coal miners in the United States has been linked to respirable crystalline silica (RCS). To better protect miners, a deeper understanding of key exposure factors is needed. As part of a larger investigation of RCS in 15 coal mines, this paper describes analysis of silica mass A Study of Respirable Silica in Underground Coal Mines:

Investigation of respirable coal mine dust (RCMD) and
Generally, it can be inferred that small mines have coal seams less than 40 in. (0.381), medium mines have coal seams with a thickness between 40–75 in. (0.165), and large mines have coal seamsJust over 40 Mt of CMM were released to the atmosphere in 2022, representing more than 10% of total methane emissions from human activity. Steam coal and lignite accounted for around 75% of CMM emissions and coking coal for the remaining 25%. Underground mines were responsible for around 70% of emissions and surface mines for the remainder.Strategies to reduce emissions from coal supply
