Redevelopment of soil carbon pools and biological ...
Surface mining is the most common technique used for mining of coal and other minerals when they occur close to the surface. In the process, the surface is completely stripped of vegetation, and the earth and rock (overburden) overlaying the coal layer is removed from large continuous areas to provide access to the coal bed or mineral of interest.

Coal seam fires destroy lives in Zimbabwe - The Zimbabwean
Coal seam fires destroy lives in Zimbabwe. Coal seam fires are leaving dozens of Zimbabwean children disabled, but no one claims responsibility for the unfolding disaster. Dozens of children who have strayed into the unprotected coal mine dumps in north-western Zimbabwe have sustained life-threatening burns, and most were left disabled.
Coal does not form quite as thought
Coal does not form quite as thought. News Nicole News 19 days ago REPORT. When plant material turns into charcoal, what specialists call coal gas can also form. Methane, essentially. He is at the origin of the infamous "Firedamp". And when it escapes into the atmosphere, it contributes to increasing the carbon footprint of coal mining.
Starch - Stärke: Vol 73, No 3-4 - Wiley Online Library
Elevation of natural alpha-amylase (α-amylase) activity in wheat grains leads to starch degradation, which can result in deterioration of bread quality. In this experiment, weather conditions (i.e., temperature and precipitation) and cultivars (spring vs winter) significantly influence α-amylase activity during grain maturation.

Soil physicochemical properties, bacterial communities and enzyme activities change with land subsidence resulting from coal mining. However, research on the responses of bacterial communities and enzyme activities to the soil properties in different degree of subsidence areas is limited. As such, we collected soil samples from a control area (C area), a …

General : Hydrothermal activity superimposed on coal?
A famous example is the already mentioned lead-zinc deposit of the Auguste-Victoria coal mine in Marl, North Rhine-Westphalia, Germany. Here the ores occur in a coal seam-bearing Upper Carboniferous cross fault, the "Blumenthaler Hauptsprung (Tertius)". The ore deposit is named "William Koehler Gang" (see figures and maps attached).

By Stuart Condie. SYDNEY--BHP Group's attempt to make Covid-19 vaccines mandatory for workers at an Australian coal mine has been ruled unlawful by the country's industrial relations tribunal because of the way it was implemented. The global mining giant had sought to deny workers' access to the Mt. Arthur mine in New South Wales state if they ...

ST45: Operating and Abandoned Coal Mines in Alberta
Coal was first excavated in Alberta during the late 1700s and early 1800s to fuel blacksmiths' forges at Fort Edmonton. In 1874, Nicholas Sheran opened the first commercial mine on the banks of the Oldman River in southern Alberta to supply coal to a local market.
