“Stoco” and “Cargot” are the same principle as “Cardox”. In the Bibai Coal Mine “Stoco” was tested for the first time July 1949 and “Cargot” August 1950. In these tests, we found many imperfect points, and then we have made the effects to improve these points. Now, these tools are used practically in this Coal Mine.
This report contains the progress improving the mechanism of these tools and results of the coal getting by these tools.
