Abstract: High concentrations of selenium (Se) and sulfur (S) often occur in overburden soils and underlying shales associated with western coal mining areas. Knowing the role of Se and S in the soil-plant-animal system is important for proper management of mine spoil reclamation. I will discuss recent findings about Se and S forms in soil, their absorption and accumulation by plants, and their...
Among various stand parameters, the density of biomass volume is oftenly used as an indicator on evaluating the forest growth succes. The forest reclamation, which is intended to restore the land cover by revegetation process, the evaluation of biomass content has been a critical issue. Forest reclamation is expected to restore the land function to a proper state that might give better environm...
Original scientific paper Evaluating the deterioration of ecological environment and vegetation of coalfields caused by China’s large-scale coal mining activities is important because of the fragile ecological environment and low temperature in cold and arid areas. This study takes the open coal pits of Haizhou, Gulianhe, and Huolinhe as examples and proposes a method for evaluating their ecolo...
Fifteen AML sites ranging in age from 13 to 35 yr in Northern West Virginia were selected from three surface-mined coal beds (Pittsburgh, Freeport, and Kittanning) to evaluate plant invasion and establishment on disturbed sites. Three 10 m by 10 m plots were randomly located on each site, and cover, density, and stem diameter of all woody plant species were measured. Herbaceous and plant litter...
Coal ash, such as fly ash (FA) and bottom (BA) is mostly generated from a Coal-fired Steam Power Generation (PLTU) process. An increase in the number of PLTUs Indonesia proportional to high volume FA BA generated, causing adverse environmental impacts if not properly treated. Various studies have highlighted potential valorization BA, including building materials, cement ingredients, concrete, ...
