Study on the Process and Mechanism of Slope Failure Induced by Mining
Mining under an open pit slope results in the collapse and slide of the slope. In this paper, a combination of methods including Google Earth and field investigations is applied to investigate the process of eastern slope failure induced by underground mining in the Yanqianshan Iron Mine over five years. According to the observed ground …

Surface Mining Techniques used in the Oil Sands
Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
