Welcome to CDC stacks

A good knowledge of the mechanism of slope failure in open-cast mines can be understood by evaluating the intrinsic and extrinsic factors and their interactions in causing slope instability, and by gathering displacement information from periodical monitoring. Surface deformations, caused by mining activities at mine sites, are conventionally measured by using survey instruments such as levels ...
