May 01 2021 Several studies have demonstrated that the hydrological impact of coal mining is proportional to the upstream areal extent of mining e.g. Petty et al. 2010 Bernhardt and Palmer 2011 Lindberg et al. 2011. An implication of this is that the presence of multiple mines in a catchment is likely to have a more substantial impact on the .

The Jharia coalfield is the most important and active minig region; it experiences groundwater inflow and affects groundwater levels in overlying aquifers and it provides the basis for a conceptual model of the hydrogeological impacts of coal mining. The several sandstone aquifers of the overburden are separated by aquitards that limit vertical hydraulic connection but the inflow responds to .
The present paper mainly deals with a case study of failed dump slope in western coalfield limited Nagpur India. A huge mass of debris flow had happened during the routine the activity of mining. The failed dump had a height of 75 m with 43 slope angle which had slipped forward by 18m. Representative loose dump material samples were collected from the site and tested to determine the .
Dec 17 2015 Indonesian Coal Mining Boom Is Leaving Trail of Destruction. Since 2000 Indonesian coal production has increased five-fold to meet growing domestic demand for electricity and feed export markets in Asia. The intensive mining is leading to the clearing of rainforest and the pollution of rivers and rice paddies. By Mike Ives • December 17 2015.
Investments in export-oriented coal mining projects are under consideration in a number of countries.

Jan 10 2015 Over-burden to coal ratio in the open cast mining is about 2 m3 tonne of coal or sometime more. Therefore the quantum of overburden generated and its proper management is the main concern area in dealing with the environmental issue of opencast coal mines. 4.
Coal is mined either by surface methods open-cut or open-cast mining or by underground techniques. In surface mining all of the rock from the ground surface to the top of the seam material referred to as overburden is removed and set aside to expose the coal which is then taken out and transported from the mine for preparation and use .
