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...

Based on the 2019 satellite remote sensing data, survey was conducted open-pit stopes of building sand mines in Shigatse, Tibet, and relationship between number area, population density district/county, as well distribution characteristics main built-up areas, administrative villages traffic roads at county level were analyzed. This study tentatively links open pit mine with human aggregation a...

Open pit mine design and production scheduling deals with the quest for the most profitable mining sequence over the life of a mine. The dynamics of mining ore and waste and the spatial grade uncertainty make predictions of the optimal mining sequence a challenging task. A new optimization approach to production scheduling based on the effective management of waste mining and orebody grade unce...

Cutoff grade is a grade used to assign a destination label to a parcel of material. The optimal cutoff grades depend on all the salient technological features of mining, such as the capacity of extraction and of milling, the geometry and geology of the orebody, and the optimal grade of concentrate to send to the smelter. The main objective of each optimization of mining operation is to maximize...

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 ...

Purpose. To develop a methodology for assessing the quality of drilling-and-blasting operations when setting side to final position. In this regard, it is necessary study nature deformations in near-side masses design open-pit contours and assess seismic impact blast waves accordance with damage near far zones from boundary, as well level generated vibrations. Methodology.A at limiting contour ...

In order to carry out an open pit mining operation, planners must periodically prepare what is known as strategic mine plan. This is a tentative production schedule for the remaining life of the mine that defines which area of a mining reserve will be extracted, in what years this extraction will take place, which resources will be used for the extraction, and how the extracted material will be...

Three-dimensional block models are the most frequently used tool for estimating mineral resources and reserves within a deposit. In open pit mining, basis of mine design long term mining schedule is calculation ultimate limit. The limit with highest profit value. Over years, different algorithms have been developed that enable us to calculate final pit: floating or mobile cone, cone II its corr...

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...

Mine planning is a typical engineering design function which integrate the disciplines of geology, metallurgy, geotechnics, mining and economics. The numerous uncertainties associated with geological understanding, the exposure of people to potential hazards in the work place and the need to provide a specific dollar outcome, requires a proper assessment of the risk. This paper identifies the s...
