La Première Guerre mondiale prive la France d’une partie des mines du Nord et du Pas-de-Calais, d’un grand nombre de mineurs et des importations de combustible allemandes et belges. En dépit des principes libéraux de la Troisième République, l’État, pour résoudre la pénurie, est conduit à intervenir de plus en plus dans la production, le transport et la commercialisation du charbon. À partir de l’été 1917, le ministre de l’Armement Louis Loucheur organise une administration spécifique, le Bureau national des Charbons, qui exerce la mainmise sur ce marché en regroupant les producteurs et les consommateurs, en fixant les prix et en réglementant la répartition. Après l’armistice, l’augmentation des prix anglais et la faible exécution des livraisons de charbon allemand rendent nécessaires le maintien du contrôle de l’administration. L’objectif du Bureau national des Charbons est alors d’unifier le marché national en essayant d’instaurer des prix de vente uniques sur tout le territoire. Mais en avantageant certaines catégories de consommateurs, il devient également un instrument de politique économique. Ce régime de guerre est supprimé brutalement au début de 1921. La France fait alors face à une crise industrielle de surproduction qui met fin à la pénurie et remet en cause l’intervention de l’État dans le marché. / During the First World War, France loses some coalmines in Nord and Pas-de-Calais, a large number of miners and German and Belgian imports. Despite the liberal principles of the Third Republic, the French State intervenes more and more into the production, the transport and the commercialization of coal to fix the shortage. From summer 1917, the Minister of Armament Louis Loucheur settles a specific administration, the Bureau national des Charbons, which controls the whole market: it gathers producers and consumers, fixes prices and rules the repartition. After the Armistice, increased English prices and insufficient German deliveries impose on the administration to keep controlling the market. The Bureau national des Charbons aims to unify the national market with single sales price for the whole country. It also becomes an instrument of economic policy since it can give some advantages to specific categories of consumer. At the beginning of 1921, this war system is suddenly dismantled. France faces then an industrial overproduction crisis which gives an end to the shortage and questions the State’s market intervention.

Thesis. (D. Tech. - Business, Faculty of Management Sciences)--Vaal University of Technology, 2010. / The study explored the South African coal mining industry and it’s role players to establish the causes of the bottlenecks/constraints experienced in the coal mining industry supply chain. A qualitative research paradigm methodology was used. Both theoretical and philosophical assumptions were utilised with inferences from and references to works by other researchers to broaden the knowledge horizons for the study. Thirteen supply chain executives and professionals from the key role players in the coal mining industry were interviewed and provided invaluable input for the study. The study determined the presence of communication barriers between the industry role players in the public and private institutions that culminated in main themes and sub-themes being established from which the industry constraints were uncovered. The study identified six main constraints affecting the various role players within the coal mining supply chain and it culminated in the model that would enable the industry to minimise such constraints. To this end, the study proposes the development of an Integrated Strategy for the Development of Coal Mining (ISDCM).The model is based on the public and private partnership arrangement that would alleviate most of the prevailing constraints when implemented. The model would furthermore have the capacity to rectify most of the existing constraints. It would be funded from the commercial sector and would operate on triple bottom lines of economic, social and environmental factors, with equal weight. This is a desirable direction for the future in order to maintain sustainable development. Emanating from the study are policy and research recommendations for the South African coal mining industry, covering the coordination of the critical areas of the proposed integrated strategy for the development of the coal mining industry. Such recommendations include further research into new coal mines and power stations as well as perceptions and expectations of potential investors in the industry, among others.
