Coal Mining Displacement

Coal Mining Displacement Ratnakar Bhengara India's coal mining industry is seeking a large World Bank loan to upgrade its mines. While displacement caused by coal mining goes unquestioned at the level of policy-making, strong reaction to the trauma it creates is building up at the ground level. WHILE Narmada, Koel-Karo and other hydro projects remain the main agenda for anti-displacement

Mining-Induced Displacement and Resettlement: Social

10/08/2012 Although mining-induced displacement is a global phenomenon, problems experienced by the displacees in many parts of the world differ greatly. The largest portion of the displacement is caused by open-pit mining (associated with the extraction of gold, copper, iron, lignite, and diamonds).

24/02/2015 was performed using laser scanning in an underground coal mine, where the displacement was induced by removing material by hand from the ribs. Volume changes as small as 57 cm3, or slightly larger than a golf ball, and as large as 57,549 cm3, were detectable in this environment, despite the change in rib surface reflectance and mine geometry. In addition to the rib displacement,

Negative Effects of Coal Mining The World Counts

Cardiopulmonary disease, hypertension, COPD, and kidney disease are found in higher than normal rates in people who live near coal mines. Displacement of Communities: All of these negative effects force people to move to other places as their air and water gets polluted and expanding coal mines make use of more and more of their habitat.

Similarity simulation study on displacement and stress

Significant changes in displacement and stress within the coal seam roof were recorded, and these increased during continuous mining activity. Displacement and stress difference on either side of the fault gradually increased and reached remarkable values with increase in mining distance. On the basis of the experiment results, water inrush is believed to be caused by the interaction between

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit

How Many People Will We Continue to Displace In the Name

Ratnakar Bhengara wrote about how displacement caused by coal mining goes unquestioned at the level of policy-making. Though Coal India had a rehabilitation policy that promised employment to those being displaced, Bhengara found that people were soon disillusioned with this. Much of the claimed rehabilitation is actually not done. By the government's own admission, only a small proportion of

Methane displacement characteristic of coal and its pore

Coal with a low metamorphic degree will experience a longer early stage of gas displacement than coal samples with a high metamorphic degree, and the cumulative gas displacement is also greater for coal with a low metamorphic degree. For the coking coal, the cumulative gas displacement reaches 0.188 mg/g at a gas driving time of 800 min, followed by anthracite and lean coal. This result occurs

Controlled Roof Collapse during Secondary Mining in Coal Mines

Secondary mining involves revisiting a mine and extracting coal from the pillars. The mining of these pillars commences from the area furthest away from the point of entry of the mine. This exercise involves cutting the existing pillars into smaller pillars called snooks. As each section is mined, the roof must collapse in a controlled manner in order to pose no safety risk to those miners
