OPENCAST COAL MINING IN WALES - foe.cymru
2016-4-6 The opencast coal mining technique is used in areas were the coal reserves are scattered in shallow and thin seams and cannot be extracted by deep mining methods (Beynon et al., 2000). The opencast process starts with exploration activities to identify where there are deposits of coal and what is the depth of the seams.

Does the UK coal phaseout spell the end of opencast mining ...
2015-11-26 Thirty years ago, at the close of the 1984-5 miners’ strike, coal mining employed around 200,000 men. Now, it employs fewer than 3,000. The great majority of our domestically produced coal now comes from opencast mining — a process that employs far fewer people than deep mining and causes enormous environmental damage.

Coal mining projects – Coal 2020 – Analysis - IEA
2020-12-18 Investments in export-oriented coal mining projects are under consideration in a number of countries. They are at various stages in the development process and here are classified as “more-advanced” and “less-advanced”1. More-advanced projects under development represent about 93 Mtpa of coal mining capacity, of which about 69% are for metallurgical (met) coal though it is less than 20 ...
