Finalist 2011 Skyscraper Competition: Underground Metropolis

China extracts an average of 2 billion tons of coal each year to satisfy its energy demands. Apart from the environmental concerns, coal mining is an extremely dangerous profession which leads to more than 6000 deaths every year.

The main concept behind this proposal is to make use of the immense coal mines as an underground city where miners will have access to a better quality of life through modern housing and recreational areas. This underground metropolis will coexist with regular cities and will integrate them through an exchange of goods and services.
