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...

Mining-induced subsidence is critical for ecological environment reconstruction and damage prevention in coal mining areas. Understanding the characteristics of surface with multi-seam first step. Surface different panel layout configurations was investigated by means UDEC numerical simulation. Based on simulation results, it indicated that configuration had a significant impact subsidence, inc...

PROBLEM An average of three workers a year are killed in surface mining operations when a piece of haulage equipment collides with another smaller vehicle or a worker on foot. Another three workers are killed each year when haulage equipment backs over the edge of a dump point or stockpile. Devices to monitor the blind areas of mining equipment are needed to provide a warning to operators when ...

Coal is the most highly used source of energy for generating power in the world. Although, it has adverse environmental impacts (Weart, 2003), it is so widely used mainly because it is relatively cheap, abundantly available and readily fits with traditional power generation technologies. It is extracted from mines using both underground and surface mining techniques – either of them having adva...

Mining for resources extraction may lead to geological and associated environmental changes due to ground movements, collision with mining cavities, and deformation of aquifers. Geological changes may continue in a reclaimed mine area, and the deformed aquifers may entail a breakdown of substrates and an increase in ground water tables, which may cause surface area inundation. Consequently, a r...

Conversion of farmland land-use matrices to surface mining is an increasing threat to the habitat quality of forest remnants and their constituent biota, with consequences for ecosystem functionality. We evaluated the effects of matrix type on bird community composition and the abundance and evenness within avian functional groups in south-west Ghana. We hypothesized that surface mining near re...

the paper is concerned with the hydrogeological appraisal of the proposed mining operations in thethar lignite field in sindh, pakistan. the thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. in the thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...

With the continuous improvement of mining technology and equipment in China’s coal mines, number working faces with high-intensity is increasing, area surface damage continues to increase compared previous years. In order ensure safe production protect overall environment area, characteristics overlying rock transmission mechanism were analyzed, forms their negative external influences evaluate...
