3. Physical stability of iron ore caves: geomechanical studies of a shallow underground cave in SE Brazil
Abstract Caves hosted in iron formations are attracting considerable interest due to their scientific and environmental value. Some of these caves are located in or near iron ore mine sites, which represent an important source of income to Brazil. However, the Brazilian legislation requires speleological studies that currently have an impact upon ore reserve

8. Neutralização de drenagem ácida de minas com escória de aciaria elétrica do forno-panela
The acid mine drainage (AMD) is formed when certain sulfide minerals are exposed to oxidizing conditions. The AMD is commonly associated with coal mining, especially in coal waste deposits that contain high pyrite (FeS2) concentration. The neutralization of AMD using alkaline materials, like limestone and steel slag is one of the useful remediation technique

10. Distribuição da brita na cidade de São Paulo - efeitos das restrições ao tráfego de veículos de carga. / Crushed stone distribuition in São Paulo city - effects on the restriction to the traffic of cargo vehicles.
The objective of this research is to demonstrate that crushed stone has a significative variation in price from the quarry to its final use. Most of such increase is not related to mining activities but to logistics activities, mainly physical distribution. This variation is highly intensified in conurbations and big cities such as São Paulo, where there ar

11. Detecção de bactérias redutoras de sulfato em efluente e sedimento de mina de urânio
One of the most serious environmental problems created by the mining industry is acid mine drainage. In one plant of Nuclear Industries of Brazil - INB, this problem is a matter of concern. The presence of iron sulfites, such as pyrite, generates water with acidity above the levels allowed by the legislation and therefore, inappropriate for releasing straigh

12. Mechanical tillage of mining degraded areas at Jamari National Forest (Rondonia - BR) / Mecanização no preparo de solo em areas degradadas por mineração na Floresta Nacional do Jamari (Rondonia-BR)
The usage of a nation s natural resources directly implies the manipulation of natural environments on the terrestrial surface. In this scenario, estimates indicate that mining contributes to one percent of the degradation of the soils of the planet. It is observable that, although it seems to be a small number, this percentage denotes a high intensity of de
