2017-6-1 In Morocco, the consumption of coal has increased since 1984 and the local production has started to decline. As illustrated in Fig. 1, from 1995, coal production showed a remarkable fall and reached its minimum in 2001.During the same year, Morocco stopped coal production due to the anticipated closure of the Mine “Charbonnages du Maroc” located in Jerada (Northeast of Morocco).

2020-11-1 Europe hosts large and growing volumes of wastes from past and present mining activities, of which coal production is the greatest single contributor. At the turn of the millennium, coal wastes accounted for some 2.4 Gt of the 5.9 Gt total mine wastes and tailings stockpiled within the EU (Charbonnier, 2001; Lottermoser, 2010).

2012-8-10 The origin of mining and mineral-processing wastes is closely related to the formation of the target resource or minerals. For example, many coal deposits exist in subsided regions resulting from mountain formation; hence, the overlays of coal resources are generally not very thick and consist of relatively inactive sedimentary rocks.
