Item type:Publication, Ciudades, territorio y ecosistemas en el Perú. Cerro de Pasco(Pontificia Universidad Católica del Perú. Facultad de Arquitectura y Urbanismo, 2026-06-08)Esta investigación forma parte de un conjunto de estudios territoriales en fase exploratoria realizados por distintos equipos del Centro de Investigación de la Arquitectura y la Ciudad (CIAC) que exponen de manera transversal los ecosistemas peruanos y las ocupaciones humanas producidas en estos. Los temas de investigación presentan las particularidades de cada caso, y también exploran el contexto urbano a partir de ciertas variables comunes. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The commitment to infrastructure: Public investment and the reproduction of water scarcity in contexts of large mining in Peru and Colombia(Universidad Catolica del Norte, 2022-01-01)Public and private policies typically consider the construction of infrastructure the most appropriate response to the problems of water scarcity and water disputes. However, infrastructure in itself not always is the solution. In this context we have the following questions: What are the logics behind the construction and implementation of water infrastructure? Why water infrastructures are not alone a solution to water stress and scarcity? How does infrastructure construction reduce or deepen inequalities in access to water? This article answers these questions by arguing that water infrastructures respond to technical-political projects of territorial control and mining expansion located in areas of mining influence, rather than aiming to solve water access and supply problems. In doing so, they ended up deepening inequalities in local water access. This article compares infrastructures constructed in the context of large-scale mining projects in Espinar, Peru and La Guajira, Colombia. The information presented was collected following qualitative methods (semi-structured interviews and situated ethnographies). Likewise, the article systematizes secondary quantitative and qualitative data provided by government institutions related to water and mining, and the Environmental Impact Studies and web publications regarding the Tintaya-Antapaccay and Cerrejón mining projects. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Maps’ agency and mountains’ multiplicity: Conflicts triggered by state maps involving pilgrims and desired mining futures in the Andes(John Wiley and Sons Inc, 2024-09-01)This article analyzes how the agency of state maps triggered conflicts between rural communities, pilgrims, and state institutions, in which some mountains emerged as multiple entities within and beyond the nature-culture divide. The Quyllurit'i shrine is the focus of an important pilgrimage in the Andes. The Peruvian state established the shrine´s Protected Area in 2010 but had been granting mining concessions around it. Confronted with a state map of the Protected Area surrounded by mining concessions, the pilgrims' organizations called for their nullification and staged protests in Cuzco city in 2016. Meanwhile, the community within which the shrine is located experienced the establishment of the Protected Area as a process of land expropriation. Its members were holders of the mining concessions and aimed to conduct mining on their lands. Mining concessions, the Protected Area, and land titles were the state maps mediating these conflicts. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Nexos entre centralidades mineras y nodos informales e ilegales de la ruta del oro(Universidad Nacional de Cuyo, 2023-07-10)Descifrar el rol de las cadenas globales de materias primas en la conectividad de los mercados con la Amazonía es clave para comprender el génesis de sus ciudades y su relación con los flujos de la ruta del oro. En el caso del suroriente peruano, específicamente la región Madre de Dios, el proceso de transformación de esta margen territorial y de frontera ha estado condicionado a los ritmos del grado de explotación de la economía mundial del caucho y oro. Se plantea comprender de qué manera el sistema de redes de ciudades mineras habilitó un modelo de organización espacial “coyuntural” para habilitar funciones urbanas permeables a las economías informales e ilegales. Desde un enfoque histórico y geográfico, se diseñó una metodología mixta con herramienta de revisión bibliográfica, sistemas de información geográfica (SIG) y campo con el fin de estudiar la configuración y reconfiguración de este espacio. Entre los hallazgos de esta metodología se discute los efectos de la urbanización en el surgimiento de centralidades que consolidaron la conectividad de los flujos de la ruta del oro, y las operaciones mineras en zonas de conservación como La Pampa. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, MODELAMIENTO DE COSTOS EN PERFORACIÓN Y VOLADURA SUBTERRÁNEA: ANÁLISIS PARAMÉTRICO DE BARRENOS CON SEGMENTACIÓN BASADA EN MACHINE LEARNING(2026-01-01)Las operaciones de perforación y voladura constituyen unidades críticas en minería subterránea por su impacto directo sobre la productividad del ciclo y los costos operacionales. Objetivo: Este estudio desarrolló un modelo paramétrico de costos directos para estimar y comparar el costo unitario (US$/m perforado) y costos normalizados por desempeño (US$/m de avance y US$/t) bajo dos alternativas operacionales de desarrollo: barrenos de 12 pies y 14 pies. Métodos: Se emplearon registros de campo de geometría de perforación, consumos de explosivos y accesorios, tiempos de operación y costos unitarios, consolidando resultados por frente/disparo y evaluando diferencias absolutas y relativas entre escenarios. Resultados: El escenario de 14 pies incrementó el metraje perforado por frente de 183.6 a 202.8 m (+10.5%) y el avance por disparo de 3.06 a 3.90 m (+27.5%). Aunque el explosivo total aumentó de 96.9 a 107.6 kg (+11.0%), el factor de potencia disminuyó de 0.61 a 0.56 kg/tn (−8.2%). El costo por metro perforado se redujo de 269.28 a 250.20 US$/m (−7.09%), con disminuciones en voladura (−13.16%) y perforación (−5.53%). Asimismo, el costo por metro de avance y por tonelada estimada disminuyeron en −19.47% y −15.15%. Conclusiones: La alternativa de 14 pies mejora la eficiencia costo–productividad al aumentar el avance efectivo, recomendándose su evaluación junto con criterios de control de contorno y estabilidad. Complementariamente, se propone un marco de aprendizaje automático y clustering no supervisado para fortalecer la predicción e interpretabilidad de los factores dominantes del costo. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, La gran minería y su impacto urbano en el siglo XXI: el suelo periurbano como escenario conflictivo en una ciudad intermedia como Cajamarca(Pontificia Universidad Católica del Perú, 2025-07-24)During the 20th century, industrial activities linked to the extraction of minerals gave rise to the implementation of settlements or urban neighborhoods as company towns. In the 21st century, mining projects have emerged that focus more on connectivity, which reduces the direct impact on the production of urban spaces. However, its effects on the urban economy can lead to important impacts on urbanization processes. This article analyzes how uncontrolled urban expansion, derived from large-scale mining activity, transforms peri-urban spaces in an intermediate city like Cajamarca: they become scenarios of conflict between rural and urban logic, with changes in land use through notarial means, outside of municipal regulations.2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Proposal to expand the pumping system for treatment and recirculation of underground water in a mining operation(LACCEI (Latin American and Caribbean Consortium of Engineering Institutions), 2024-01-01)This work presents a proposal for the expansion of a water treatment system inside an underground mine, and thus optimize the water resource present in the mining operation. For this purpose, the design parameters of an existing two-stage pumping system ...2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Mining, infrastructure, and mobility in the Andes(Routledge, 2024-01-17)Large-scale mining projects have been associated with both the construction of infrastructure and changes in local spatial mobility patterns. However, few studies have paid attention to the specific role that the infrastructures of mining play in shaping...1
