 · Alluvial soil plays an important role in ground subsidence caused by coal mining and groundwater extraction. Coal mining areas covered with thick alluvial soil (CMATASs) are widely distributed in China and ground subsidence in these areas exhibits unique features—for instance the maximum subsidence is greater than the extracted coal seam thickness. Consequently studies on the

Global Sand Mining Is Destroying the Planet and Costing

 · Extracting Sand. What experts do know though is that extracting sand in unparalleled quantities comes at a growing cost to people and the planet. Sand mining destroys habitats dirties rivers and erodes beaches many of which are already losing ground to rising sea levels. When miners dig out layers of sand riverbanks become less stable.

Experimental Study on Recovery of Nickel from Nickel

It is known that to extract nickel from nickel-bearing laterite ore is not an easy job. By reducing roast-magnetic separation an effective result is achieved in this research in dealing with nickel-bearing laterite ore due to its simple technology process and the high nickel recovery. Nickel-bearing laterite studied in this research is mainly characterized by fine disseminated grain size and

Model for the prediction of subsurface strata movement

The mining speed in the model is 50 mm h-1 which represents the mining advance rate of 12 m d-1 in the prototype system. The materials for physical model are combinations of gypsum concrete sand and lime. The grain size of the sand is within 0.15–0.5 mm. The lime is made from freshwater limestone and through-burned. The gypsum is calcined.

A Monitoring System of Sand Mining in Large Rivers and Its

Sand mining is one of the major sustainability challenges of the 21st century. Rates of extraction are surpassing sand supply and ensuing sand starvation is adversely impacting channel-floodplains and deltas. Therefore quantifying sand mining s location and extent through global monitoring and detection particularly in fluvial systems is becoming a priority.
