In underground mines the methane, accompanying the exploitation of the primary mineral - hard coal, and is discharged into the atmosphere in two ways: with ventilation air (70%) and methane drainage system (30%). The development of methane from coal seams is important for the following reasons: as it can be used for the production of electricity and heat or in cogeneration. This is because the emission of methane into the atmosphere contributes to the greenhouse effect. Currently the work is being carried out by t...

Over 400,000 shells of different calibers were dumped in Burgas Bay after the end of WWI. The operation, under the coordination of the British forces, was completed without the dumping areas to be clearly mentioned and mapped, allowing us today to assume that they can be anywhere in Burgas Bay. Many other shells were also dumped in the sea at the end of WWII. During the first phase of expansion of Burgas harbor, carried out between 2001 and 2006, a great deal of unexploded ammunition, originating from both WWI and...

Twenty years after finishing the dam ?unovo on river Danube about 15 km beneath Bratislava were after regular controls gradually exclude from system some observation boreholes. There were realised new investigation boreholes. The main reason of these boreholes was verification of the soil characteristics in depth where the periodical changing of water in Danube and in reservoir had negative influence on the permeability characteristics. One of the most important factors of safety is filtration stability of granula...

With the advance of mining to greater depths, the fully protecting safety pillar of shafts is progressively diminishing. Thus a certain part of the mineshaft and of the protected area on the surface is influenced by undermining. In such a case, it is necessary to assess the expected effect of mining on the mineshaft and the surface objects in relation to the preservation of their stability. Subsequently, it is necessary to carry out direct measurements of movements, and, if the case may be, deformations both in th...

Detecting people in videos or images in order to interpret their behaviour is nowadays an important part of safety and security monitoring. Detection of persons in videos is more challenging than detection of any other moving objects, be it animals or vehicles. This paper reviews the recent work on a developing tool - STATBOX for spatial analysis and modelling. STATBOX concept is based on the video data collection for a given territory, which can be taken using different devices such as mobile phones, surveillance...
