Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.

A new mining scheme by employing the induced caving mining method to exploit hanging-wall ore-body during the transition from open pit to underground mining is proposed. The basic idea is to use the mined-out area generated by the planned mining of the hanging-wall ore-body to absorb the collapsed slope body, so as to avoid the influence of the inner-slope mining to the normal open-pit mining

Open-pit mining is one of the most commonly used techniques to extract minerals from the Earth. The process, which is also known as "opencast mining," "open-cut mining" and "strip mining," is used when deposits are located close to the surface, and entails digging or blasting from the ground level to extract ore.
