Determination of the Limit of Oxidation in Zones of Sub-outcropping Chipanga Coal Seam, Moatize Coal Basin, Mozambique

Abstract

Moatize Coal Basin (MCB) in Mozambique is a graben with sediments of Karoo age with thick coal seams that are under exploration and exploitation by the Vale Moçambique company. Presently, the exploitation is as an open-pit mine and in the future the works will extend to the area where formerly underground mines were under exploitation. It is well known throughout the World that Moatize basin is a World class deposit for coking and thermal coal and therefore Vale Moçambique is developing studies to rationalize the coal resources of the area.
