At the Yauricocha mine, there is an issue where the steel ribs used in the production stopes fail within a period of less than two months. This leads to an increase in support costs and delays in ore extraction, as the mining operations have to be halted for the reinstallation of the steel ribs.Furthermore, this can even result in ore loss. These problems arise due to the generation of high stresses caused by the massive mining technique known as Sub Level Caving. In the production stopes, it is necessary to maintain a minimum operational section of 3.0 meters to accommodate the entry of the 6-cubic-yard low-profile loaders. This compliance ensures ore recovery. To achieve this objective, a new support design is proposed formining. The Peruvian arch is a reinforced concrete arch element with high-strength structural steel placed between the steel ribs in the production stopes of the Yaur...

In all mining operations, a reconciliation system is necessary, which allows measuring the performance of the processes involved in obtaining the final product, from the reserve-resource models, through mine design, mine planning, mining production, until culminating in the metallurgical process. It is through the relationship between the ore received (ground ore) with the ore sent to grinding (short-term model), that reconciliation factors will result for tonnage, grade and metal. Subsequently, they will be evaluated in a monthly, quarterly and / or annual period of time, and will help to refine the processes and sub-processes of the short-term model, as well as the mining process and the metallurgical process. The results will be reflected in the reduction of the differences in the reconciliation factors for tonnage, grade and metal, this reduction must be supported over time; In other...

Mining projects require high investments, and their development or closure is dependent, among other factors, due to the variation in the price of commodities in the international market and due to the depletion of their mining reserves, respectively. The Rosita Mine located in the northeast of Nicaragua is a good example of how the price of metals and other social factors, among others, can affect the development of a mine, and may lead to its final closure, the Rosita Mine began industrial operations at late 1950s and closed in the mid-1970s. The geological and tectonic conditions of Nicaragua have allowed the evolution and location of different types of metallic deposits, characterizing the country as the largest gold producer in Central America during the last century. The Rosita Mine is characterized by a Skarn Cu-Au-Ag deposit located in rocks of the Todos Santos Cretaceous formati...

Quality program is important for achieving the objectives of mining projects. They consist of the quality management plan, quality management and assurance (QA) and quality control (QC). They are a tool implemented by the mining companies in order to have valid information that allows the elaboration of resource mineral estimation and reserve mineral estimation studies. The International Standard NI 43101 contains the guidelines for the elaboration of the reports to stock exchanges and bankable feasibility study. The content of the standard is applied in the elaboration of the Quality Program and thus it can be implemented during the activities of a project such as field geology, drilling campaigns, geotechnical, hydrogeological, hydrological studies, topography, security, environmental evaluations and water quality studies. In this sense, the Quality Program requires highly specialized ...

In Peru there is the only boratifero deposit of the salar type, the Laguna Salinas, which is characterized by being formed under certain environmental factors of evaporitic origin, determined by endogenous and supergenic processes (endoreic system), now, we must understand how it was formed and what is its relationship in geological time with respect to its chemical equilibrium. In Lagunas Salinas, ulexite is extracted, which is a hydrated calcium and sodium borate, which we see that due to its characteristics it is possible to give a relationship on its occurrence over other similar borates and the reason for its dominance in the area over other boratiferous species. The objective of the research is to determine the mineralized horizons of ulexite in relation to the chemical equilibrium between the formation temperature and the water content that these boratiferous species present. The ...

The hamlets of Puruay Bajo and Lluscapampa Baja are located north of the city of Cajamarca at Km. 4.5 of the Cajamarca - Bambamarca highway; in this area we determined the different volcanic stages of pyroclastic flows of the Tual - Puruay Pyroclastic Volcanic sequence and the third stage of the San José sequence, these rocks belong to the Yanacocha Volcanic Complex of Neogene Miocene age (23.03 - 5.3 Ma). This complex is divided into Volcanic Sequences: Tual Puruay, Atazaico Volcanic Center, Regalado Volcanic Center and San José. The geological mapping was carried out with the respective sections that helped in the elaboration of stratigraphic columns. In addition, samples were collected where we proceeded to carry out the petrographic study either in thin section (SD) and polished section (SP) of the most representative ones. With the stratigraphic columns, petrographic studies ...

The mineral resources´ estimation is a fundamental issue in the existence of a mining-metallurgical company. The amount of current software and methods has allowed the quality of the estimates that are made to increase, however, there are still variables that are determined based on criteria and experience that influence the accuracy of the generated model. In geostatistics, the size of the support is of great importance for the creation of the model. In this work, two block models of different support are compared, created from the same data, with the same estimation criteria, to recognize the difference between the two, and the real production data, concluding that no significant variation is observed on this scale.

The objective of this study is to characterize the composition of a diatreme breccia by means of a lithological description in order to characterize the mineralized economic replacement levels of the linked stratum type (mantles/bodies) related to Zn – Pb – Ag mineralization, in the zones favorable areas located at the edges of the diatreme breccia, in the lower levels of the Islay mine in order to elevate the mineral deposit from small mining to a category of medium mining.From the analysis it was determined that the Islay mine is associated with a diatreme of phreatomagmatic origin, composed of different lithofacies of breccias, tuffaceous levels, tectonic breccias and local fractures that could be cemented by economic mineralization, by identifying the different facies that make up the phreatomagmatic gap we could determine the presence of economically exploitable mineralized bodi...

Skarn-type deposits show complex mineralogical and textural relationships because of the variety of geological processes involved in their development. Mineral associations can be further complicated by supergene leaching and oxidation. Consequently, hydrothermal alterations constitute complex geochemical signatures to be analysed under a number of factors in these mineralised systems, which are conclusive in vectoring these types of deposits. This study is proposed in order to understand these alterations and to propose their usefulness in the exploration of Cu-Zn skarn deposits. The methodology of bibliographic research and case studies was used, from three main sources of data: information from the Mesozoic sedimentary belt of the Inter-Andean Cordillera and the Yauli dome, case studies from different parts of the world and analysis of the geological, magmatic and petrological conditi...
