It is said that the coal crisis of today is in no way related to business cycles but arises from the growing structural change in the field of energy consumption. In our country, the coal mining industry has received various forms of protections from our government. If the coal mining industry in the future must reach a state of efficency whereby he is able to do his business without any government protection at all, what is to be done in the present days?
The most important demand for coal has been in the energy market. In this market the coal is challenged by the petroleum and will be challenged by the atomic energy. The situation of this competition is not in favour for coal. Coal as a chemical raw material also has received a challenge of the petroleum, and the situation is difficult for coal.
However in the author's opinion, this difficulty comes from the present technical level of coal chemical industry because our industry has lagged in a research to develope potentialities of coal. And the author believes that there are some new fields of chemical industry to utilize some particular properties of coal, such as high molecular weight, large numbers of condenced aromatic rings, etc., Then the author would propose to begin some research programes to develope a new chemical industry of coal.
Another field in which the coal has a special advantage is the metal refining industry, especially iron and steel making. As a reducing agent of metals, coal has many advantages, but the coking coal which is used for the present blast furnace is in poor production and inferior in quality in Japan. This is one of many reasons of particular difficulties in our coal mining industry.
This is the reason that we must attempt to develope some new iron making process without present high shaft furnace. Then the author would emphasize new developments of an iron making process with low shaft furnace which needs not the coking coal of high quality or some new processes with direct charge of coal.
