十几年来煤矿技术人员一直致力于巷道全机械化掘进课题的研究。60年代初,由于煤巷掘进面临巷道管理、矿井瓦斯等方面特殊困难的挑战,有关研究工作一直延续至今。目前德国纵截割头式部分断面掘进机装机功率100～350kW,有效重量24～115t,平均掘进速度7～8m/d(最大可达20～30m/d),代表了目前部分断面掘进机的技术状况。 1 限定截割范围的因素随着机械制造业的发展和对截割技术要求的不断提高,不得不开发相应的截割技术。 More than a decade coal mine technicians have been committed to fully mechanized roadway tunneling research. In the early 1960s, due to the challenges of special difficulties in roadway management, mine gas and other aspects of coal tunneling, the research has continued to this day. At present, the longitudinal cutting head type partial boring machine of Germany has an installed power of 100-350 kW, an effective weight of 24-115 t and an average driving speed of 7-8 m / d (up to 20-30 m / d), representing the current partial boring machine Technical condition. A limited range of cutting factors With the development of machinery manufacturing and cutting technology requirements continue to rise, have to develop the appropriate cutting technology.
