"Blue Mining" The Future of Mining Initial Considerations for Underground Pumped Storage Plants

Due to continuously growing resource demands and increasing requirements for sustainability, safety and environmental protection on the other hand, the mining industry is being subjected to these additional requirements. Over the past few decades progress has been made in all topics. In 1987, the United Nations published the following in the Brundtland Report: ?development that meets the needs of the present without compromising the ability of future generations to meet their own needs.?[5] The term ?Blue Mining? means to work sustainably, economically, ecologically, and efficiently while also improving ergonomics, for example by increasing automation. An example of how mining can actively be involved in energy management will be shown. Initial evaluations of underground cavitites were done for purpose of energy storage. The planning and construction of underground pump storage plants both in active and inactive mining operations was also investigated.
