The research is based geomechanical qualification of rock mass, in the underground mining works of the Asonambile Concession (Nambija Mining District), through the Bieniawski’s RMR system (1989) and the Barton’s Q index (2000) in addition to the empirical correlations to determine the Hoek’s GSI index (2002), which allowed defining the geomechanical parameters and with it, the behavior and geotechnical quality of 2,473 linear meters of underground galleries. The geomechanical parameters indicate that mining works located up to 50 m deep from the surface, present a minimal risk of rock bursting; while those located from 100 m, present violent rock bursting, causing instability. Geotechnical tests "in situ" and laboratory, carried out between 2010 and 2014 by the Instituto Nacional de Investigación Geológico, Minero y Metalúrgico (current Instituto de Investigación Geológico y E...

The province of Soto Norte (Santander), Colombia, is known for its mining tradition in the municipalities of Vetas and California. Four centuries ago, mining exploitation was developed and environmental liabilities were generated, which put at risk in activity. Many defend the topographic and vegetal restoration of exhausted mining operations, burying them or sealing them. However, when these works have brought out mineral outcrops of worldwide interest or have allowed access to galleries excavated many centuries ago that have provided valuable archaeological remains that have served to learn a little more about our history. Therefore, in the face of the generally accepted idea that the restoration of a mining waste inevitably passes through its burial or sealing. Geotourism around the mining industry is an emerging sector that contributes not only to the diffusion of the interesting geo...

The zone of left-lateral shear of the Chonta fault takes place a rotate deformation, arriving a moment in that the fractures of tension and the shear set are distributing parallelly, to the to continue the deformation left-lateral set R they act like a new shear zone and it with the combination of the new set of shears R and P, it gives place to the formation of a fracturing zone to way of braid. Then this hypothesis would be expandable to the other centers of veins of the San Genaro zone and to the different points of the Mining District of Castrovirreyna. The deflections of the Chonta structure (by example in the quadrangle of Huachocolpa), the rhombus form of the sinclinório of Castrovirreyna with sub parallel axial axis to the Chonta fault, allows to give a second hypothesis at regional level, that the sinclinório of Castrovirreyna could be part of a structure of the pull-appart ty...

An environmental liability in Peru is located in Puno, in the district of Ananea, originated by informal mining activities 90 years ago. Phytoremediation was carried out with Festuca Dolichophylla, a plant native to the area, with the assistance of ammonium thiosulfate as an accelerator. Soil samples were extracted from the areas impacted with mercury. The research used a factorial design with the following response variables: the concentration of total mercury (HgT) in soil and plant tissues, and as factors the level of ammonium thiosulfate in the soil and the time of plant growth. The soils of the Ananea-Puno district have neutral pH, elemental mercury constitutes 56% of the total amount of mercury in the soil. THg concentrations in the soil range from 44 to 53 mg/ kg, which is almost 2 times higher than the upper limit for mercury content (24 mg/kg) in extractive soils in Peru. The BA...

This research approaches the effects that the water quality of Rimac river has presented opposite to the development of the mining activity in San Mateo’s district of Huanchor located in Huarochirí’s province in Lima. The area of study is a zone where the mining polymetallic activity has developed from many decades behind approximately from the 30s, epoch in which there had not the current requirements of the environmental legal regulation and for such motive we have nowadays catalogued in the zone 21 environmental mining liabilities between mine entrance, tailing ponds and infrastructures seated on the banks of the Rimac water and of it’s principal tributaries like Blanco and Aruri rivers which nowadays are important sources of lixiviados to Rímac river water, due to the fact that they aren`t being handled by the private company and for the State. The quality water investigation...

La tesis de investigación aborda los efectos que ha presentado la calidad del agua del río Rímac frente al desarrollo de la actividad minera en el distrito de San Mateo de Huanchor ubicado en la provincia de Huarochirí del departamento de Lima. El área de estudio es una zona donde la actividad minera polimetálica se ha desarrollado desde muchas décadas atrás aproximadamente desde los años 30, época en la cual no se tenían las actuales exigencias de la normativa ambiental legal y por tal motivo tenemos actualmente catalogados en la zona 21 pasivos ambientales mineros entre bocaminas, relaveras e infraestructuras asentados a orillas de las aguas del Rímac y de sus tributarios principales como son el río Blanco y el río Aruri, los cuales actualmente son fuentes aportantes de lixiviados a las aguas del río Rímac, debido a que no están siendo manejados ni por la empresa priva...

In the month of November 1981. The city of Cusco was invaded by hundreds of peasants from the neighboring district of Maras on a sacrificial march, claiming the benefits of their salt mines for the whole town, demanding the departure of the trading company (EMSAL). ) and requesting the municipalization of their resource. Fleetingly, the name of Maras appeared in the information media of Cusco and the capital of the Republic. The terms of his claim did not attract much attention, although the State was forced to accept them. In the opinion of many, the Government of that time erred in weakness by handing over to a district municipality the commercialization of the salt to be withdrawn from the state company, the "only one empowered by law to commercialize salt, a basic and first-priority industry" (D.L. 17387-PCM-69).

Formal mining in Oyón, Lima Region, is evaluated: the damages and benefits caused to water, soil and the population, its profits and what is delivered to the country by the Uchucchacua Mining Unit. It includes the analysis of what it contributes to the National Budget and to the Provincial and District Municipalities (economic, objective impact), the feeling of the population (social, subjective impact, perception), the effects of its actions on the environment (environmental impact, objective) and what is obtained by the company (economic profits, objective). There is an additional impact on subsidiary activities, basically suppliers, but in any case, given that the manufacturers of the really expensive mining equipment are foreign companies and the complexity of this analysis, it has been discarded, since it would be minimal for the country. There is an impact in terms of decreased un...
