3. Indicator kriging applied to RMR geomechanical modelling in a Pb-Zn deposit case study
Abstract The opening of a mining enterprise requires knowledge of the geomechanical characteristics of the mineral deposit, which will be worked according to the use of parameters of stability and/or resistance of the material, as well as the discontinuities present in the rock. In this study, the Rock Mass Rating methodology was used to propose a geomechani

4. Obtaining geotechnical parameters from correlations between geophysics and CPT tests in tailings dams
Abstract This article introduces a hassle-free methodology for geotechnical parameters to be obtained from correlations between geophysics and CPT field tests in tailings dams undergoing the decommissioning process, which are reasonably representative of site conditions, from the very early project stages, with extensive coverage of all impoundment parts, wi

5. Peculiarities of drilling and blasting in underground small-scale mines
Abstract Artisanal and Small-scale Mining (ASM) is a prominent activity in the extractive industry: considering only gold, it produces about 20% of the world market supply. Despite this fact, ASM is generally associated with the negative aspects of its environ mental impact, and operational research is generally neglected. This article empha sizes the peculi

6. Analysis of the impacts of slope angle variation on slope stability and NPV via two different final pit definition techniques
Abstract The traditionally and widely used Lerchs-Grossmann algorithm presents well-known limitations that newer propositions attempt to overcome. The direct block schedule (DBS) methodology, which has gained relevance with computational advances, obtains the final pit as a natural result of production sequencing, different from Lerchs-Grossmann-based algori

8. Application of ISO 31000 standard on tailings dam safety
Abstract Tailings dam safety is a frequent subject of discussion during mining project development. However, due to recent accidents with these structures, this issue has become even more prominent. A highlighted point is the risk management, which can be defined as the identification, analysis and maintenance of risks at acceptable levels during the design,

9. DNPM actions on the implementation of law 12.334/2010: from the ordinances and inspections to the SIGBM
Abstract As defined in PNSB - Law 12.334/2010 (Brasil, 2010), the DNPM, which manages the Brazilian mineral resources, is also responsible for overseeing the safety management of tailings dams in the country. The purpose of this article is to present the actions carried out in this context by the Department since the enactment of the Law in 2010, such as: el

10. Recent Developments in Damage Identification of Structures Using Data Mining
Abstract Civil structures are usually prone to damage during their service life and it leads them to loss their serviceability and safety. Thus, damage assessment can guarantee the integrity of structures. As a result, a structural damage detection approach including two main components, a set of accelerometers to record the response data and a data mining (

11. Factors affecting road crash modeling
Abstract Road accident fatalities have been on an increasing trend for the last decade or so in India. Hence traffic safety management has emerged as a topic of discussion for researchers all over the world. Hence accident modelling on different factors causing them has to be conducted. Accident modelling helps us to know the real causative agents behind an
