The paper proposes a Plan of Prevention of Disasters based on a final product: a map – image of vulnerability that was gotten using the digital cartography from a satellite image “IKONOS”. That map – image has permitted the location of vulnerable areas in case of earthquakes taking into consideration the slopes and the building type and use. A study area located at the north of Lima, the District of Los Olivos, was chosen.

The first task of an Environmental Impact Assessment (EIA) study is to carry out an environmental diagnosis of the affected area or to be affected by a certain activity. This implies knowing the environmental components and their interactions, also characterizing the environmental situation from that area before the implementation of the project. In the present investigation of a company in the paper industry, the purpose is to determine the impact it produces on the environment, and above all to reach a mitigation plan by preparing proposals and its feasibility through cost / benefit analyzes. .

This article shows the results of the research project "Socio-Economic Impact of Pollution of Beaches in Lima" after monitoring water quality in 1999, carried out in five beaches (La Herradura, Agua Dulce, the Weeds and Makaha Marbella ). Marbella and Herradura were the most polluted beaches. They socioeconomic surveys conducted in different districts of Lima. 58% of respondents showed a preference to go to the beach in his free time during the weekends in the summer. Of these respondents, 71% preferred to go to the beaches of the South that the beaches of Lima, where he carried out the project, and this due to contamination.

The research focuses on the environmental problems generated by informal gold mining by dredges in the Peruvian Amazon, specifically the Yaguas River Putumayo River Basin. Monitoring results effected between 09 and 15 September 1,999, show mercury in river sediments Yaguas (0.3189 and 0.3911 mg Hg / kg), which proves the technical basis for the ability of mercury deposition. The vessels (dredgers) that perform the extraction of gold does not meet the essential environmental standards set by the MEM. As urges broader assessment involving the determination of the toxicity of mercury in the ecosystem of the area through conventional water quality parameters and sediment considered in addition to, or confirming biomarkers negate the hypothesis on the introduction of mercury into the chain and its arrival at the man.

This article shows the results of the research project that included air quality monitoring at eight stations located in different districts of Lima and Callao in 2000. Air quality monitoring basically consisted of measuring material Particulate, lead and arsenic in PM10 in three seasons of the year, late summer, winter and spring. The concentrations at the end of the summer were higher than those of the rest of the year, mainly due to the weather conditions. The monitoring station, located in the Comas district, had a PM10 concentration of 240 mg / m3. A concentration of 1,601 lead in PM10 was found at the Callao monitoring station.

The environmental effects produced by the artisanal mining activity in the town of Relave, cause environmental problems and problems in the health of the inhabitants, which can be remedied with the proposal and execution of an environmental management in accordance with the reality of the area. The research project carried out by teachers and students from the Universidad Nacional Mayor de San Marcos, during 2001, demonstrates that the existing working conditions lack technical supervision and it is necessary to establish environmental management, as well as guidelines so that artisanal activities in gold mining are the most optimal. This task must be carried out with the participation of institutions such as the Congress of the Republic, the National Environment Council, the Ministry of Energy and Mines, the Ministry of Health, the Provincial Municipality, Universities and the Ministry ...

Mine equipment selection is a complex task due to numerous technical, geometrical and economical variables involved. The variety of equipment manufacturers and agents carrying different models, types and sizes make the selection procedure even more complex. The mine planner does not have a tool to correctly select the equipment or fl eet for a project. Simulation fi lls the gap and contributes to this goal. This study tries to apply deterministic and probabilistic simulation approaches in selecting mining equipment using fi eld data from two surface mine operations. The deterministic model uses a one year production plan from a quarry. The equipment fl eet is selected on the basis of minimum unit cost for both drilling and excavation-haulage equipment fl eets. For the probabilistic approach the GPSS language is applied. Programs were prepared for various combinations of loaders and haule...

La elección óptima de equipo en minería superfi cial es una tarea compleja donde intervienen muchas variables técnicas, geométricas y económicas en un ambiente donde existen muchas marcas, modelos y tamaños que compiten por el usuario. El técnico que efectúa la selección no tiene una herramienta apropiada que le permita evaluarlos y decidir por el mejor. La simulación contribuye a efectuar esta selección. En este estudio se desarrolla los modelos determinístico y probabilístico de simulación aplicados a equipos de minado con datos de dos operaciones superfi ciales. En el caso determinístico se simula la producción proyectada de un año de una cantera y en base a costo unitario mínimo se elige la fl ota de equipos tanto en perforación como en acarreo. En la simulación probabilística se usa el lenguaje GPSS para simular modelos de excavación y acarreo para varias comb...

This article summarizes the study carried out, the objective of which is to assess the landscape impact of the Utcubamba River Falls, which is part of the research project for the management of natural landscapes for ecotourism purposes in the middle basin of the Utcubamba River. What is remarkable about the study is that it addresses a relatively new aspect; but, very important for the use of natural resources. In the valuation of the landscape there is a clear conflict between different approaches; the method used for the valuation of the landscape units in this work is the one proposed by Ignacio Cañas Guerrero and María A. Ruiz Sánchez. This method is briefly described, and later on, the aim is to combine the different possible approaches in the valuation of the landscape, thus considering physical, artistic and psychological attributes.
