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.

1991-1-1 Opencast coal mining 1942-80 Opencast coal production began in earnest as an emergency wartime measure in 1942, in order to increase guaranteed coal supplies.' As this was considered to be essential for the defence of Britain, all operations were controlled by the government (Defence Ministry).

2021-6-21 Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

The reclamation of surface (opencast) coal mines is not always successful; there remains a legacy of degraded land that burdens local communities. This article evaluates a community-oriented, low-cost means of geoecological regeneration, the “Cradle for Nature” strategy, which uses mosaic tree planting to foster positive natural ecological processes.
