本文是根据1985年9月西德开采与工作面运输研究所所长亨格尔博士来中国讲学的有关资料编译整理的。一、刨煤机在西德机械化采煤中的地位西德三十年来通过发展煤炭开采机械化使煤矿的生产能力有了大幅度的提高。 1955年西德有2400个回采工作面,工作面商品煤平均日产量是190吨,全年总产量是1亿5千万吨。 1970年工作面减少到500个,而工作面商品煤平均日产量增加到1200吨。工作面主要是用刨煤机,500个工作面年总产量为9000万吨。
This article is based on September 1985, West German Mining and Face Transport Institute, Dr. Heng Geli to China lectures compiled compiled. First, plow mechanized coal mining in West Germany’s position West Germany over the past 30 years through the development of coal mining mechanization so that coal production capacity has been significantly improved. In 1955, West Germany had 2,400 working face faces with an average daily output of commercial coal of 190 tons and a total annual output of 150 million tons. In 1970, the working face was reduced to 500 while the average daily production of commercial coal on the working face was increased to 1,200 tons. Face is mainly plow, 500 face a total annual output of 90 million tons.
