Solar water pumping system for water mining environmental control in a slate mine of Spain

The location of mining areas is subject to the availability of resources and the capability to extract them. As these areas are usually isolated or of difficult access they lack any means of electric infrastructure as its installation can be rather costly. Therefore the use of local energy resources, such as solar energy, becomes relevant for the mine energy supply. This study carries out a solar pumping project in a slate mine in Galicia (Spain) related to automatic control systems in surface water management affected by waste from the extractive activity and thus abiding with environmental legislation.
