基于新型履带式全液压钻机的螺旋钻进试验研究

Testing Research on Auger Drilling by New Type Crawler Hydraulic Drilling Rig

摘要:

采用了新型履带式全液压钻机在阳泉煤业集团二矿进行的煤层螺旋钻进试验，试验表明使用该履带式钻机减少了钻孔的辅助时间，提高了钻孔效率。通过本次试验发挥了钻机及钻具的优势，并总结了螺旋钻进技术一些注意事项。

Abstract:

The coal bed auger drilling was tested in Yangquan coal group with new type crawler hydraulic drilling rig. It showed that the auxiliary time of drilling was reduced and the drilling efficiency was improved. The drill and drilling tools brought advantages in this test, and a lot of construction cautions of auger drilling technology were summarized.
