Potential ecological impacts of climate intervention by ...

Apr 13, 2021· As the effects of anthropogenic climate change become more severe, several approaches for deliberate climate intervention to reduce or stabilize Earth''s surface temperature have been proposed. Solar radiation modification (SRM) is one potential approach to partially counteract anthropogenic warming by reflecting a small proportion of the incoming solar radiation to increase Earth''s albedo.

Permeability Test of Soil by Falling, Constant Head ...

A separate constant head method for granular soils has been recommended by Indian Standards (IS: 2720 – Part 36, 1975). This method is suitable for disturbed granular soils containing less than 10% soil passing 75 um IS sieve. This range of particle sizes is used for the construction of embankments and base courses under pavements.

Glossary of Mining Terms - Coal Education

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
