1969年我国第一次利用钻井法开凿了淮北朔里南风井,多年来,钻井法的施工装备、施工技术和工程管理都积累了丰富的经验,同时也摸清了存在的主要问题。为了发展这一综合机械化的凿井方法,使之广泛地应用于钻凿各种类型的煤矿立井,其关键在于如何提高钻井机的钻凿效率。
In 1969, for the first time, China used the drilling method to drill the Shuifeng south shaft in Huaibei. Over the years, drilling rig construction equipment, construction technology and project management have accumulated rich experience and also found out the main problems. In order to develop this comprehensive mechanized sinking method, which is widely used in drilling various types of coal mine shaft, the key is how to improve the drilling efficiency of the drilling machine.
