Underground Gasification of Coal
Journal of the Fuel Society of Japan, 1965 Coal assumes an important role as energy souces along with hydraulic power in our country. In order to supply energy at low cost each coal mining company has tried to carry out the rationalization of industry in many respects.Hereafter it is necessary for us not only to promote the mechanized extraction of coal, but also to study positively the new ...
