Underground coal mines explosions generally arise from the inflammation of a methane/air mixture. This explosion can also generate a subsequent coal dust explosion. Traditionally such explosions have being fought eliminating one or several of the factors needed by the explosion to take place. Although several preventive measures are taken to prevent explosions, other measures should be considered to reduce the effects or even to extinguish the flame front. Unlike other protection methods that remove one or two of ...

The paper summarizes the results of assessme nt of geo mechanical characteristics of rock samples collected from the Sibiu C ounty: Valea StrГўmbului-Rasinari and Valea Marajdia. The rock characteristics are infl uenced by climate factors, in particular temperature and humidity. When the phenomenon of frost occurs, rock stretches and some strains are acting that lead to a deterioration of the structure and internal stability, thereby reducing the characteristics of resistance and strength. Within this scope, sever...

The nature conservation is an essential part of the human efforts for preservation of the natural landscape for the future generations. Both the living and the non-living parts of our environment are the subjects of bioconservation and geoconservation. Geoconservation aims to preserve the natural diversity of the non-living environment including bedrock features, landforms and soil features and processes. In the last two decades Bulgarian geologists have made effort s to recognize its geological heritage. In 2003 ...

Centuries-long exploitation of rock salt from Tuzla salt deposit has produced significant deformation of the ground surface and buildings in the town of Tuzla. The southern edge of the deposit dips beneath the northern part of the town. Although relatively small size, the deposit represents an extremely complex geological body The slow, natural processes of dissolution of the deposit's eastern part were accelerated by industrial exploitation of saline water (bri ne) that lasted over 100 years. Exploitation of the ...

The paper describes results from 18 months data collection and analogue modeling of “rain water – calcrete” interaction. The expe riment is based on leaching by natural rain and snow-melting water of material from diff erent soil and undersoil layers, containing various amounts of carbonates. It confirme d that rain and snow-melting water, circulating through the soil, undersoil and the underlying rocks, dissolves calcium rich minerals. Under dry weather and relativel y high temperature the hydrogen carbonat...

The area under study is located in east Azerbaijan and southwest of Ardabil. In this area the volcanic rocks are placed over the Oligocene and lower Miocene clastic sedimentary rocks and under lower Pliocene epiclastic sedi ments. Therefore, their age is middle and upper Miocene. These volcanic rocks have been extruded in dome shape from the fissures of an eruptive caldera. These domes are rich in silica. From the boundary to the center of caldera, these domes are categorized into three types with regard to their ...

Cyanides/cyanates of sodium or pota ssium not only during centuries but over millenniums were used in methods for extraction the gold from ores, and further in refining of obtained golden m ud. In those processes the cy anides/cyanates still are not changeable. According to the huge amount of tr eated ore, it is expected that the amount of waste treated materials also be huge. We lding and brazing of golden parts frequently are obvious in usage for the purposes of gold jewel making. Therefore, it becomes reasonabl...

The metallogenic district of Linares-La Carolina (JaГ©n, Spain) consists of dyke mineralizations mainly of galena, accompanied by blende, chalcopyrite and barite. It is located in the head water catchment of the Guadalquivir River, the Andalusian main river, in the sub-basins of the rivers Guadiel and Grande. Associated to these abandoned mines, relatively extensive areas occupied by spoil heaps and tailing impoundments exist and constitute potential sources of water pollution by metals and semimetals. In addition...

Methods for gas extraction are currently ranked among clean coal technology. Coal gas is a normal part of coal deposits a nd its mining reduces methane emissions. Underground coal gasification is a non-traditional mining method that also allows use of coal deposits which are not possible to be mined by traditional methods. These technologies bring both positive and negative aspects aff ecting the environment. This contribution is covering the influence of gas extraction from coal deposits on the environment accomp...

The process of the development of a proper environmental strategy and its successful implementation into everyday life has become one of the most important ideas of the 21 st century. Typically, the major issue related to this strate gy is its financial aspect; however certain regional disparities or local specifics may also represent a significant problem. In addition to the state environmen tal policy, the government of the SR has also developed basic concepts of environmental programmes. The main objective of t...

In the Jiu Valley coal basin (Romania), fr om over 2 thousand million tonnes of balance reserve, more than 60% are involved in the bituminous coal seams no.3 and no.5, which ensure 90% of the coal output of the entire basin. The thick coal seams no.3 is mined in slices with longwall mining system and roof control by caving. Because of the short mining panels, often under 300-400m, the star ting costs of mining panels become very important at the entire panel coal reserves. Th erefore, in this paper there are prese...

Determining the stress around a mining excavation is a complex issue of Geomechanics and implicitly of the mining area. The evaluati on of stress state is essential, but very difficult to obtain, due to the interaction of the instrument ation with the rock massif. The measurement methods, together with the devices and the methods of processing and interpretation of data, ensure and create the possibility of knowing the degree of dependence between the measured effects in terms of time, and the factors causing them...

Induced and natural seismicity discrimination in seismically active regions remains one of the complicated problems. An example of unusual seismicity pattern, which is currently recognized by seismologists as triggered seismicity due to oil and gas field production is considered in this work. We ha ve analyzed the seismicity behavior in seismogenic zone without any human-made activity as well as in hydrocarbon production area. We conclude that examined areas are characterized by the same dynamic regime. It follows...
