煤矿用防爆柴油机车在世界上一些主要国家已有数十年历史,一般均认为具有机动、安全及经济等优点,这种机车在西德、加拿大、法国、捷克、英国、罗马尼亚、澳大利亚、苏联及美国等国家都已作为井下运输的主要动力设备。我国近几年来,随着对井下运输机械化要求的不断提高,正在抓紧研制工作,到目前为止,40马力轨道式防爆 Explosion-proof diesel locomotives for coal mines have been established in some major countries in the world for decades. Generally, they are considered as maneuvering, safety and economic advantages. They are used in West Germany, Canada, France, the Czech Republic, Britain, Romania, Australia, the Soviet Union And the United States and other countries have been as the main power equipment downhole transportation. In recent years, with the continuous improvement of the mechanization requirements of underground transportation, our country is paying close attention to the research and development. So far, the 40-horsepower orbit explosion-proof
