The purpose of this paper is to investigate the potential for use of UAVs in underground mines and present a prototype design for a novel autorotating UAV platform for underground 3D data collection. The mining industry has recently shown increased interest in the use of unmanned aerial vehicles (UAVs) to assist in everyday operations [20, 11, 4]. Above ground, small UAVs are in some cases a mo...

In open-pit mine planning, the design of the most profitable ultimate pit limit is a prerequisite to developing a feasible mining sequence. Currently, the design of an ultimate pit is achieved through a computer program in most mining companies. The extraction of minerals in open mining methods needs a lot of capital investment, which may take several decades. Before the extraction, the p...

A token economy that used trading stamps as tokens was instituted at two dangerous open-pit mines. Employees earned stamps for working without lost-time injuries, for being in work groups in which all other workers had no lost-time injuries, for not being involved in equipment-damaging accidents, for making adopted safety suggestions, and for unusual behavior which prevented an injury or accide...

Mixed integer programming (MIP) models are used for long-term production scheduling of open pit mines. However, formulations based on binary variables for mining blocks require too many variables and are often difficult or impossible to solve. This paper presents and tests alternative MIP scheduling models that have reduced the number of binary variables and solution times, thus increasing effi...

global navigation satellite system (GNSS) receivers are usually unable to achieve satisfactory performance in difficult environments, such as open-pit mines, urban canyons and indoors. Pseudolites have the potential to extend GNSS usage and significantly improve receiver performance in such environments by providing additional navigation signals. This also applies to asynchronous pseudolite sys...

Abstract The number of abandoned mines is continuously increasing in the world. sustainable exploitation these a top priority globally. Pit lakes created mining sites provide benefits and present risks for region. This paper presents methodology to assess natural hazards related pit lakes. proposed framework based on well-established internationally accepted risk management standards allows ass...

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...
