Economic Geology is a subdiscipline of the geosciences. It devotes itself to the scientific study of the Earth’s sources of mineral raw materials and to the practical application of the acquired knowledge. Considering the life-cycle of a mine, economic geology leads in the search for new mineral deposits and in their detailed investigation. It contributes to economic and technical evaluations, which confirm the feasibility of a project and end with the physical establishment of a mine. While mining goes on, economic geology provides many services that assist rational exploitation, foremost by continuously renewing mineable reserves and by limiting effects on the mine’s environment to a minimum. Possible negative impacts of mining include surface subsidence, lowering of the water table, various emissions and mechanically unstable or environmentally doubtful waste rock dumps. In the phase of mine closure, economic geology helps to avoid insufficient or outright wrong measures of physical and chemical stabilization, recultivation and renaturalization.
