Mining activity monitoring, volume calculations, data for information systems of mining companies, decision making and planning, reclamation proposals are some of the most important fields, where photogrammetry can be used in open pit mining. Nowadays mostly digital methods find their utility in providing stereoscopic digitisation of a current situation of mining, precise orthophotos and digital terrain models. There are requirements for high precision especially in heights due to volume calculations and therefore high-resolution aerial images with low flight altitude are taken for the open pit mining purposes.

This book describes the fundamental and theoretical concepts of optimization algorithms in a systematic manner, along with their potential applications and implementation strategies in mining engineering. It explains basics of systems engineering, linear programming, and integer linear programming, transportation and assignment algorithms, network analysis, dynamic programming, queuing theory and their applications to mine systems.

This paper describes some mitigation/remedial measures used in Chilean open pit engineering practice to deal with some common pit slope problems. These measures include the use of controlled blasting techniques, slope depressurization and pit dewatering, use of retaining dikes, buttresses and removal of material in unstable slopes, and the filling of pre-existing underground excavations and surface craters.  <...>

This tutorial provides an introduction to the common tools and functions contained within Deswik.CAD in an Open Pit Hard Rock operation, however as this tutorial is an introduction to Deswik.CAD functionality, the learning’s can be applied generally.

This tutorial is designed to be used in conjunction with the training data folder 3.01 Intro to CAD Open Pit Hard Rock containing all of the training data, software files and a completed set of CAD exercises. <...>

With the removal of the majority of the shallow mineral reserves there has been an increase in the mining depths in the South African mining industry. This has, in turn, changed the industry’s and stakeholders’ perceptions of risk associated with mining-induced instability. In recent years the increased mining depth, particularly in open pits, has led to an increase in pit slope failures, which has highlighted the need for appropriate and effective pit slope management programmes. Such a programme comprises many facets, including mine hazard plans, regular slope inspections, cleaning of interim and final pit faces, blasting practices, histories of failures, pit depressurization, stormwater control and evacuation procedures. However, it is arguably in the field of slope monitoring that the most significant strides have been made in terms of new technologies and best practice in open pit mining geotechnics, with the introduction of technologies such as laser scanners and slope stability radar. This paper seeks to illustrate the operational benefits associated with the implementation of new technologies into open pit mining, using AngloGold Ashanti’s Geita Gold Mine in Tanzania as an example. <...>

The purpose of this paper is to present the way how the Geotechnical Group of Chuquicamata Division works on geological, geotechnical and hydrogeological characterizations, analysis and design of slopes, the control of slope excavation to develop the proposed designs, and the monitoring and control of slope behavior. On the other hand, it also describes the interaction of this group with the Planning and Mine Operation groups, and the applied research and technological innovation that the Geotechnical Group develops in order to maintain a continuous improvement and, at the same time, to secure the fulfillment of mid and long term mining plans. <...>

The empirical derivation of the minimum berm width and the formulae presented by the various design criteria are different due to the input parameters selected, thus resulting in a range of minimum berm widths that can be calculated for the same set of rock mass and geometric conditions.

Безопасность ведения горных работ призвана обеспечить охрану труда, т.е. создание таких условий, которые исключили бы воздействие на работающих опасных и вредных условий труда.
В производственных условиях безопасность горных работ определяется безопасностью оборудования, производственных и трудовых процессов.
В условиях производства горных работ весьма значительно влияние природных факторов, поэтому необходимо систематически следить за их изменением и своевременно принимать меры по устранению их вредного, опасного влияния на производство.

В книге освещаются вопросы совершенствования технологии горных работ при открытой разработке сложных месторождений цветных металлов. Обобщен опыт и теоретически обосновываются рациональные методы оконтуривания рудных тел с использованием ядерной геофизики, повышения эффективности шарошечного бурения и качества дробления горных пород. Приведены исследования эффективности технологии выемки руд сложного состава экскаваторами, обоснования основных параметров системы разработки и рационального использования горнотранспортного оборудования. Изложены вопросы борьбы с пылью и газами в карьерах, прогнозирование эффективности разработки крупных рудных месторождений.
Книга рассчитана на инженерно-технических работников предприятий, научно-исследовательских институтов и организаций, а также может быть использована студентами горных вузов и учащимися техникумов.
