What Should We Do When The Drilling Machine Is Stuck?
When the DTH Rock Drilling Rig is under construction, it is most afraid of encountering a stuck drill. However, if it is encountered, there is no way. We must deal with it in time. Today DTH Drill Rig Manufacturer will solve this problem for you.
First of all, let's first talk about what is stuck, which is the phenomenon that all the columns and tools can't be lifted, lowered or turned in the well. If this phenomenon occurs, the drilling machine can't work normally.
Drilling is the strength of the current drill bit, and the condition of the broken wing has been basically eliminated. Once there is a special situation, a seamless pipe with a diameter and a diameter difference can be used. The pipe is filled with butter, asphalt, etc., and is connected with the drill pipe to enter the bottom of the hole. The broken wing at the bottom of the hole is pulled out, and the rock powder at the bottom of the hole is blown off before salvage.
Drills that can't be lifted in a tough situation can't be lifted. The impactor doesn't ring. At this time, only the external torque or auxiliary tools are used to help promote the drill, and then the drill is turned, and then the drill is promoted until the fault occurs. Lift it off. When re-rocking, first add pressure, and then gradually increase the propulsion until the normal working pressure.
