Causes and Prevention for Sinkhole in Limestone Mine
In recent, the placement of backfill in underground mines has emerged as a new paradigm in research as it not only improves safety but also allows disposal of byproducts including coal ash. In this regards, this paper addresses the backfilling challenges in limestone mine to prevent sinkhole and subsidence. Limestone mines, generally regarded as being safer than coal and metal mines, have been ...
متن کاملMine water treatment with limestone for sulfate removal.
Limestone can be an option for sulfate sorption, particularly from neutral mine drainages because calcium ions on the solid surface can bind sulfate ions. This work investigated sulfate removal from mine waters through sorption on limestone. Continuous stirred-tank experiments reduced the sulfate concentration from 588.0mg/L to 87.0mg/L at a 210-min residence time. Batch equilibrium tests showe...
متن کاملAnalysis of the Potential for Use of Floating Photovoltaic Systems on Mine Pit Lakes: Case Study at the Ssangyong Open-Pit Limestone Mine in Korea
Recently, the mining industry has introduced renewable energy technologies to resolve power supply problems at mines operating in polar regions or other remote areas, and to foster substitute industries, able to benefit from abandoned sites of exhausted mines. However, little attention has been paid to the potential placement of floating photovoltaic (PV) systems operated on mine pit lakes beca...
متن کاملA Brief History of Mine Ventilation
Observations of the movements of air in underground passages have a long and fascinating history. Between 4000 and 1200 BC, European miners dug tunnels into chalk deposits searching for flint. Archaeological investigations at Grimes Graves in the south of England have shown that these early flint miners built brushwood fires at the working faces—presumably to weaken the rock. However, those Neo...
متن کاملSustainable Development of Abandoned Mine Areas Using Renewable Energy Systems: A Case Study of the Photovoltaic Potential Assessment at the Tailings Dam of Abandoned Sangdong Mine, Korea
As mineral resources are depleted, most mines are typically abandoned and left unattended, resulting in serious social problems that impede sustainable development of these areas. The mining industry has recently introduced the use of renewable energy systems to solve the problems. This study assessed the photovoltaic (PV) potential of an abandoned mine tailings dam at the Sangdong mine in Sout...
