Abstract Large-scale open-pit mining activities have profound impacts on the surrounding landscape and environment. At cessation of mining, rehabilitation large void spaces can be achieved by pit-lake filling, where water body provides a confining pressure mine surfaces, reducing both likelihood slope failure need for ongoing maintenance. Although pit-lakes present range long-term benefits, geo...

Mining enterprises are widely introducing digital technologies and automation is one of such tools. Granularity monitoring, namely, the size determination rock mass pieces a common operational component processes that extract minerals by open-pit mining. The article proposes an approach that, in addition to lump distribution, makes it possible estimate form distribution as well. To investigate ...

Production scheduling (planning) of an open-pit mine is the procedure during which the rock blocks are assigned to different production periods in a way that the highest net present value of the project achieved subject to operational constraints. The paper introduces a new and computationally less expensive meta-heuristic technique known as imperialist competitive algorithm (ICA) for long-term...

This paper raises important questions about the way we approach numerical analysis in rock engineering design. The application of advanced models is essential to adequately analyze and design different geotechnical aspects pit-to-cave transitions. We present a critical review methods centered around hypothesis that model not, cannot be, perfect imitation reality; therefore, modelling large-scal...

Purpose is to substantiate the use of an in-pit crushing and conveying technology at open pits with complex structure working zone, which technological includes inclined steeply conveyors for improved economic efficiency mineral mining deep levels. Methods. The study applies a method including: technical-economical analysis practice enterprises, experience using units concentration plants pits;...

Controlling rockfall-related risks is a requirement for safe pit operations and primarily mitigated through adequate bench geometry design implementation. This paper presents method rockfall hazard analysis in-pit potentially impacting external sensible areas, adapted from natural analyses. The considers the susceptibility to rockfalls pre-mining, originated failures, those initiated as flyrock...

The mining industry is highly suitable for the application of robotics and automation technology, since the work is arduous, dangerous, and often repetitive. This paper presents a broad overview of the issues involved in the development of a physically large and complex field robotic system—a 3500-tonne mining machine (dragline). Draglines are “walking cranes” used in open-pit coal mining to re...
