实践证明,斜井掘进远距离管路输料喷射混凝土支护施工,是一项行之有效的先进技术,对加快斜井施工速度非常有利。它具有施工速度快、工效高、经济合理、安全可靠、机械化程度高、能减轻工人的劳动强度等优点。陕西铜川基建公司二、四处,在斜井坡度为12.5°～19°的砂岩、页岩及泥岩中, Practice has proved that inclined tunneling long distance pipeline material jetting shotcrete support construction is an effective advanced technology, to speed up the construction of inclined shaft speed is very beneficial. It has the advantages of fast construction speed, high work efficiency, economic rationality, safety and reliability, high degree of mechanization, and reducing the labor intensity of workers. Shaanxi Tongchuan Infrastructure Company two or four, in the inclined shaft slope of 12.5 ° ~ 19 ° sandstone, shale and mudstone,
