Abstract
The primary objective of this study is to demonstrate the use of the <em>in-situ</em> nanoelectronics purification technique of open pit hydrops for the green mining technology. Open pit mining can result in serious groundwater seeping, while direct drainage of the open pit hydrops may cause pollution of surface water and decrease of ground water, which has a negative influence on the vulnerable ecological environment of Shendong mining area. It is necessary to exploit a hydrops purification technique in open pit that could lead to a positive evolution of the open desert mining area. Based on the climate characteristics and the open pit conditions, the <em>in-situ</em> nanoelectronics purification technique and treatment process of open pit hydrops was presented. The natural oxidation pond has been applied, which had been high-effectively applied into Majiata open pit mine area. It has both theoretical and practical value for the green mining technology with similar conditions.
Highlights
In the 1970s, the contradiction between the America’s widening coal production scale and the water environment has been increasingly acute
More and more people pay attention to the phenomenons, such as the river bed dewatering, the water quality deterioration and the ecological system damage caused by the mining (Chen et al, 2010), at the same time, the contradiction between the coal resources mining and water consumption caused different industries competitive of the water resources (Hickcox, 1980)
Open pit caused by organic farming open-pit mining is the equivalent to a large well, which is the objective collection conditions from atmospheric precipitation, surface runoff and underground water gushing (Maddalena and Carlo, 2004)
Summary
In the 1970s, the contradiction between the America’s widening coal production scale and the water environment has been increasingly acute. The pit water caused by organic farming open-pit mining discharged in the form of waste water, destroy the circulation law of drainage, waste the water resources, cause the decline of ground water level, at the same time, the harmful substances in industrial waste will pollute ground water (Plotkin et al, 1979).
