Chile Miners To Be Rescued Through Unconvnetional Drilling
Source: #-Link-Snipped-#
33 miners are stuck inside a mine in Chile in area almost equal to a 1 BHK flat.
Dr Andrew Wetherelt, a senior lecturer in mining engineering at the University of Exeter, said Chile’s state-owned Codelco mining company is planning on using a massive Strata 950 ‘raise boring’ drill to carve a hole 66cm wide to reach the miners trapped under solid rock 700m below the surface.
The rescue team is drilling a pilot hole before finalizing the plan. The 5 August collapse of the mine’s main access shaft happened about 400m below the surface. This was above where the miners were working at the time. The group took refuge in a gallery approximately 688m below in an area that stretches about 2km long, which should leave enough space for the likely restless men to walk around.
