Environmental Influence of Coal Mining Thesis Essay

Deprive mining not merely exacerbated the negative environmental effects of past forms of mining but also added one other dimension for the environmental trauma of the location. As a result of this form of mining it was found that in the 1920s that mining in the areas of Appalachia had had a significant influence on waterways and acid drainage.

Influence of Coal Extraction Operation on Shaft Lining ...

2014-4-27 · Influence of Mining Width. Figure 5 shows the influence of mining width, when the mining width is 100 m, the maximum stress increases dramatically and it was almost 2 times higher than that of the 50 m wide. Therefore, due to the increase of mining width, there is a significant stress concentration occurs in shaft lining near the mining panel.

2012-11-1 · Loading schemes. There are three typical mining layouts in coal seam, protected coal mining, top-coal caving and non-pillar mining, and the different mining layouts cause stress redistribution, the corresponding stress states. The redistribution of stress is important to roadway support, stability analysis and safe mining.
