The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...

This study addresses the following questions in the context of a developing country. Do crimes increase following natural disasters? Does an upcoming election or the presence of a strong local media, which potentially increases the incentive of the government to provide disaster relief, mitigate the effect of disasters on crime rates? I find that crime rates tend to increase following moderate ...

A new type of cosmic-ray experiment is under construction in the Pyhäsalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 m of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground ...

There is a great threat to the production safety of coal mines caused by mine water disasters. Traditional identification methods are not adapted efficiency today’s mining and do offer advantage accurate detection in real-time. In this study, Mayfly Algorithm (MA) was used optimize Long Short-Term Memory (LSTM) network, combined with laser-induced fluorescence technology, apply it sources for p...

abandoned surface mine excavations can be a major environmental, social and/or human healthproblem for the mining industry as well as for the community living nearby. this problem is exacerbated by therapidly growing population encroaching on areas of historic mined lands. the aim of this studywas to assess thesafety status of the historic nyala mine excavation with the purpose of coming up wit...

In order to prevent landslide and collapse in the mining area, it is essential not only gain a full understanding of surface deformation information about open-pit area surrounding dumps, but also closely monitor development deformation. Small baseline set (SBAS) technology can be applied extract high-resolution spatial-temporal from areas. Due decoherence, however, difficult obtain effective o...

The activities of mining exploitation in Campo de Jales were performed in an uncontrolled way and gave rise to serious environmental contamination: rubbish depositories have been accumulated with no treatment or maintenance. An investigation developed around Jales Mine showed the existence of some chemical impact originated from the waste produced during mining activities. Some "black spots" fo...
