TB880E型掘进机是我公司1997年引进的,先后在西康线秦岭隧道和宁西线磨沟岭隧道施工中使用,经历了不同的地质条件下的施工。根据经验,我们发现,在施工过程中,根据具体地质情况合理地选择掘进参数对保证施工工期起着十分重要的作用。在此,笔者结合TB880E型掘进机在秦岭隧道和磨
TB880E roadheader was introduced by our company in 1997 and was used in construction of Qinling tunnel on Xikang line and Mogouling tunnel on Ningxi line. It has undergone construction under different geological conditions. Based on experience, we find that reasonable selection of driving parameters according to specific geological conditions plays an important role in ensuring the construction schedule during the construction process. Here, I combined with TB880E roadheader in Qinling tunnel and mill
