Horizontal bores and drains are crucial infrastructures for maintaining the stability of large open-pit mines. Induced deformations as result mining activities infiltration water from surface catchments during heavy rain events can cause build-up pore pressures in brown coal batters. This potentially lead to catastrophic slope failures. boreholes commonly installed at shallow inclines typically...

Dump engineering is an important part in production processes of open-pit mining. In order to complete the mine production tasks smoothly, it is necessary to make the most of land possessed by the dump in an economical and reasonable way. In the paper, we use the dump of Qidashan iron mine which belongs to Anshan Iron and Steel Group as an engineering background to achieve the aim of improving ...

Production planning of an open-pit mine is a procedure during which the rock blocks are assigned to different production periods in a way that leads to the highest net present value (NPV) subject to some operational and technical constraints. This process becomes much more complicated by incorporation of the uncertainty existing in the input parameters. The commodity price uncertainty is among ...

The Certej basin is situated in the North of Deva town, in Apuseni Mountains and was an important nonferrous mining region. In present the mining activities were stopped, but the acid mine drainage is still affecting the underground water quality. Acid Mine Drainage takes place where sulphide-bearing material is exposed to oxygen and water. This drainage water is characterized by low pH, high s...
