The Netherlands terminate coal mining
On December 17, 1965, the Dutch government announced the complete termination of coal mining. The consequence of the decision for employment, the social and economic structure and cultural and social developments in South Limburg were enormous, as all the Dutch mines were located in this area. Seventy-five years of mining had turned the south of the province of Limburg into one of the most densely populated areas of the Netherlands. The mines had resulted in the creation of supply industries and an infrastructure of roads, railways and waterways, mainly aimed at the transportation of coal within the Netherlands and abroad.
