author delivered a memorial speech on“Studies and surveys onutilization of coal resources in Hokkaido”for a 1961 Prize for the coal section, awardedby the Fuel Society of Japan.
Of the four main islands of Japan, Hokkaido is rich in natural resources, especiallyin coal deposits ranging up to 10, 000 million tons, which amounts to half of Japan'stotal coal resources.
However, Hokkaido is still sparsely populated;industrially speaking it is one of theleast advanced areas in Japan today.
In post-war Japan, re-evaluation of Hokkaido resulted in the enactment of“TheHokkaido Development Law”in 1950, and succeeding to the First 5 Year Plan startedin 1952, the Second 5 Year Plan was brought underway in 1958 which willbe foll -owed up with another new long-term plan storting 1963 .Promotion of industries and utilization of the abundant natural resources are expected to be the center point ofthe new Hokkaido Project.Since 1948 several surveys were made under the abovecircumstances with reference to the Hokkaido development plans, and also studies onutilization of coal, by the author, Mr.W.Hirota and their co-workers during thepast 12 years.
In this paper the author emphasized the utilization not only of organic substances incoal but also of ash of low grade coal resources as raw material as well as of coalmine gas by draining abundant Ishikari coal field firedamp, and that those materialscan be best utilized in large quantities at coal field sites.
The content of said paper:
1) Objectives of the surveys and their relation to the research on coal utilization.
2) Survey on the fuel consumption per family per year in Hokkaido.
3) Survey on the quality of coal covering all workable coal fields in Hokkaido.
4) Studies on utilization of coal ash-manufacturing of gypsum slag cement using slag-tapping boiler slag as raw material.
5) Studies on the caking pniperty of Hokkaido coals and their characteristics at theplastic stage in carbonization.
6) Studies on the high pressure coal hydrogenation process with special emphasis onproducing aromatic chemical compounds.
Lastly the author has expressed his view on future industrial development in Hokkaido.
