The drainage of abandoned mines leads to several ecological problems, particularly the acidification of surface freshwater systems and heavy metal contamination. In order to study the possibility of using the behavioural early warning responses of Portuguese indigenous benthic invertebrates to detect an acute short-term pulse of Acid Mine Drainage (AMD), experiments with the Multispecies Freshw...

This proposal describes a program of work designed to contribute to the Navy's capabilities in mastering the mine warfare problem by developing and demonstrating fundamental capabilities needed for an Autonomous Oceanographic Sampling Network (AOSN). This includes the integration of AUV, ship, and moored sensors into a network test range. This range will support the development, testing, and de...

ground vibrations caused by blasting are undesirable results in the mining industry and can cause serious damage to the nearby buildings and facilities; therefore, controlling such vibrations has an important role in reducing the environmental damaging effects. controlling vibration caused by blasting can be achieved once peak particle velocity (ppv) is predicted. in this paper, the values of p...

The issues related to improving the efficiency of automatic ventilation control systems mines that regulate air supply mine in accordance with need are considered. During tests such a system 3RU OAO Belaruskali, shortcomings its existing, implementation, associated incorrect choice most difficult-to-ventilate direction, were revealed. possibilities implementing strategy, which automatically det...
