poland is a traditional mining country ranking high in europian mining. a considerable part of polish national-gross-product comes from mineral resources. a large number of the working people work in the mines and related industry. research and educational centers depending on mining are well grown and are of great importance. the major mining commodities of poland are: coal, brown coal copper,...

theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. they are typically in a non-equilibrium state with respect to their surroundings. hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...

One of the main concerns of an underground coal mining engineer is the safety and stability of the mine. One way that the safety and stability can be ensured is to know and understand the coal mine geology and how it reacts to the mining process. One technique that has shown a lot of success in the coal mining industry for geologic technical evaluation purposes is the coal mine roof rating (CMR...

Implementation of clean mining technology at coal mines is crucial to protect the environment and maintain balance among energy resources, consumption, and ecology. After reviewing present coal clean mining technology, we introduce the technology principles and technological process of paste backfill mining in coal mines and discuss the components and features of backfill materials, the constit...

OBJECTIVES We examined elevated mortality rates in Appalachian coal mining areas for 1979-2005, and estimated the corresponding value of statistical life (VSL) lost relative to the economic benefits of the coal mining industry. METHODS We compared age-adjusted mortality rates and socioeconomic conditions across four county groups: Appalachia with high levels of coal mining, Appalachia with lo...

Surface coal mining has become the ideal method for extracting coal from the Appalachia Mountains. However, surface coal mining generates large amounts of waste which may decrease the water quality in central Appalachia. This research is an attempt to determine whether surface coal mining negatively impacts water quality. This research consists of a literature review in addition to an analysis ...

Appalachia has higher morbidity and mortality compared to the nation, and suffers greater socioeconomic disadvantages. This article investigates the relationship of coal mining to elevated mortality rates in Appalachia. Total mortality rates for the years 1999–2004 were investigated in a national county-level analysis that included coal mining as the primary independent variable. Counties in Ap...

Mining can become more sustainable by developing and integrating economic, environmental, and social components. Among the mining industries, coal mining requires paying a serious attention to the aspects of sustainable development. Therefore, in this work, we investigate the impacting factors involved in the sustainable development of underground coal mining from the structural viewpoint. For ...

the gravimetric method is one of the most effective ways for the detection of subsurface structures such as tunnels, faulting, mineral deposits with the required density difference, especially in areas with rough topography and tectonized formations. it is possible to provide a more suitable model for better interpretation of the gravity anomaly. inverse modeling of gravity data is the most eff...

Coal mining is one of the core industries that contribute to the economic development of a country but deteriorate the environment. Being the primary source of energy, coal has become essential to meet the energy demand of a country. It is excavated by both opencast and underground mining methods and affects the environment, especially hydrological cycle, by discharging huge amounts of mine wat...
