自七十年代初发生世界性能源危机以来,西德政府开始重新注意增加煤炭生产,提出一个加强煤矿开拓掘进技术的研究计划。其中强调发展机械化掘进的重要性,把掘进工艺每个环节的机械化及开拓掘进技术经济合理化作为特别重要的研究课题。 1974年国内能源紧张的情况下,西德政府和各州政府在执行能源开发的计划中,为研究掘进机械化和开拓技术经济合理化,到
Since the onset of the world-wide energy crisis in the early 1970s, the West German government has begun to re-pay attention to increasing coal production and put forward a research project to strengthen coal mining technology. Which emphasizes the importance of developing mechanized excavation, mechanization of excavation every aspect of mechanization and mining excavation technology and economic rationalization as a particularly important research topic. In the context of the domestic energy shortage in 1974, the West German government and the state governments in the implementation of energy development plan, in order to study mechanization of tunneling and explore the technical and economic rationalization, to
