摘要
多功能反井钻机是在现有反井钻机基础上开发出来的,既可以向下钻扩孔又可以向上钻扩孔,借鉴了Atlas-Copoco公司Robbins类型反井钻机的设计经验,填补了国内反井钻机的一项空白,为国内反井钻机的发展和更广泛的应用提供了一种新的思路。
Multifunctional raise boring machine is developed on the basis of existing drilling machines.Not only can it drill down,it can also drill up.It draws on the design experience of the Robbins type raise boring machine and has filled a domestic gap in the design of raise boring machine,providing a new vision for the development and wider application of domestic raise boring machine.
