| Abstract: | This article introduces two useful methods,i.e. downing the hole hammer with ream drilling and casing synchronously and claning the slant borehole with reverible air to blow connector as withdrawing bit. The two methods, or tools,used in geological hazard controlling engineering,can avoid some jamming events and burying accidents and improve conditions of the anchor rope taking into the hole when the bore hole in the collapse and slide coused loose deposits. The article also introduces the caution and typical cases in coustruction. |
