After a year's investigation at Taiheiyo Kushiro colliery of a high-output, high-productivity, low-cost mining system, we started operating a so-called SD face in April of 1967. This system uses shield supports and a drum cutter to obtain a high production from a short face with rapid advance.We encountered many difficulties mainly because of unfavorable roof conditions. However, we have now overcomed them and have achieved a cost reduction of 1, 500 Japanese yen per ton of coal in the panel.SD face No.14 is being operated at present under extremely stable conditions, giving the following results: face length, 50 meters; output, 1, 800 to 2, 000 tons per day; rate of face advance, 10 to 15 meters per day; OMS, 50 to 60 tons.
