当回顾战后我国(日本)煤矿采煤技术时,我们认为,首先是从工作面采用金属支架开始,而后转向采用刨煤机、滚筒采煤机的机械化采煤和水力采煤等。后来由于采用了新技术,使生产能力迅速提高,出现了工作面集中及合理化的新局面。并且通过认真的技术革新克服了随着向深部过渡而带来的恶 When reviewing the post-war coal mining technology in China (Japan), we think that the first step is to start with metal supports on the working face and then to mechanized coal mining and hydraulic coal mining using plows and drum shearers. Later, due to the introduction of new technologies, the rapid increase of production capacity, there has been a new situation of face concentration and rationalization. And overcoming the evil brought along with the deep transition through serious technical innovations
