Abstract
1. The study of 'the organization of coal mine industry (constituting factor), as a premise to the growth of industry, is important for the industrial development in present Japan. For, this reason, I have taken up the case of coal mines in Northern Kyushu, (Chikuho), explained where the problem exits, and having considered the order of importance in the composition of prime cost, discussed the following three points: (1) Nature of labor factor. (2) Obtainment and consumption of essential material. (technicality of management.) (3), Marketability. 2. As for the nature of labor power, labor range and form of mustering based on labor composition may be considered. The topographical and geological difference affects the length of mine shaftt and the number of blasting, and thus determines the labor distribution. The birth place of worker and the method of mustering determine the scope of labor range and the quality of the workers, and further condition the growth of coal mine industry. 3. The main point of the nature of technical management exists in the condition of obtaining and consuming essential material. Capital and national policy affect mining efficiency and control the growth. The difference in sectional distribution has occured due to the effects of these conditions. Here exists the geographical factor. 4. The distance of the market affects the coal price and controls the development of related industries; This charactetistic appears as the amount of shipment from this region ; and. the fact that the quality and substance of it vary in each gun (district) and ku (ward) has been noted. This difference is due to geographical reasons. 5. From the above mentioned, it may be considered. that between geological factor (A) and productive conditions .(labor B, Market -C) there exists a. correlation of A:B:C. The balance and alternation of there factors are the causes of growth, and of which varied effects appear in each gun and ku. Consequently, for industrial development the proper arrangement of coal mine industry is deemed necessary.
