Abstract:

Raise boring machine does little damage to wall rocks,is safe and efficient and requires less labor intensity,so it is widely used in the excavation of raises that are higher than 60 m.Since the hoisting and conveying system in Sunite Jinxi mining company has the capacity to carry large-diameter cutter head,raise boring machine is used to construct passageway ventilation shaft.The paper elaborates the process of the drilling selection and construction.The industrial application shows that in the construction of passageway ventilation shaft higher than 60 m with the diameter over 2.0 m,raise boring machine is fast and efficient,safe and reliable,reduces labor intensity,and has less effect on wall rocks.The construction effect is good and the machine is worth promotion in vertical shaft excavation in similar mines.
