Surface subsidence caused by underground coal mining has received wide attention due to its impact on the ecological environment. To obtain first-hand data subsidence, we arranged line measurement stations in area of Weiqiang coalfield and implemented surface movement observation at first working face obtained dynamic curve. The curves reflected initial, active declining stages each point a bas...

Mercury (Hg) is a toxic trace element emitted from coal conversion and utilization. Samples with different ranks gangue Ningwu Coalfield are selected investigated in this study. For understanding dependence of mercury distribution characteristics on coalification degree, Pearson regression analysis coupled Spearman rank correlation employed to explore the relationship between sulfur, ash coal, ...

This paper investigates silicosis as a disabling disease in underground mining in the United Kingdom (UK) before Second World War, exploring the important connections between South Africa and the UK and examining some of the issues raised at the 1930 International Labour Office Conference on silicosis in Johannesburg in a British context.
