The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamation process. The effect of BFGD on the soluble salts composition and chemical properties of sodic...

Abstract Sustainable reclamation practices for large surface coal mines in USA semiarid environment contribute to the quality of environmental on a long term basis where resources are protected future generation. Land, after reclamation, must be suitable previous use greatest economic or social values community area. In climate USA, non-developed land is mainly utilized crops, grazing, and wild...

Mining developments in alpine coal mining areas result slow or rapid ground subsidence, which can lead to melting and collapse of permafrost. This paper integrated unmanned aerial vehicle (UAV) images satellite-based SAR interferometry monitor intensive surface subsidence during reclamation. Digital Surface Model (DSM) acquired from UAV was first used evaluate the changes reclamation scheme on ...

Spontaneous combustion of coal is one of the most horrifying hazards in coal industries, especially in underground coal mines. Thus having a prior knowledge about the occurrence of this phenomenon in underground coal mines is of crucial importance in preventing this process, loss of life, huge economic loss, and environmental pollution. The aim of this work is to determine the spontaneous combu...

Overlapped areas of crop and coal production are responsible for national food security mineral resource supply. However, long-term mining urban rural construction have continuously impacted the structure functions original agricultural landscape ecosystem in area brought serious ecological problems. On basis results remote sensing image classification Zhaogu area, this study explores spatio-te...

Coal mining activities carried out by PT. PQ causes a change in the environmental setting so that its function needs to be restored according designation. The return of land is through reclamation activities. Reclamation need evaluated order continue make improvements and optimal results. This study assesses success rate PQ. aims examine evaluate based on Decree Minister Energy Mineral Resource...

A large-scale land reclamation project is now being carried out at Penny's Bay, Lantau Island, Hong Kong. The completed reclamation will provide 2.8 km 2 of land for the construction of the new Hong Kong Disneyland and other essential infrastructure developments. The impact of this project on various aspects such as ecology and environment has been widely discussed. This paper studies the chang...

Mining activities have a positive impact that can generate income for the state, but also cause negative impacts in form of soil damage, vegetation and animal losses to disrupt ecosystems. Therefore, it is necessary carry out reclamation with revegetation using local plant species. PT Berau Coal has conducted sugar palm (Arenga pinnata). The success growth post-mining land influenced by several...
