Causes and Solutions of Drill Stuck in DTH Drilling Rig

Why does the drill stick when the DTH drilling rig is used? How to solve? Let's follow the DTH drilling rig YK manufacturer to find out.

1. Bit broken wing;

2. The newly replaced bit is larger in diameter than the original one;

3. Machine displacement or drilling tool deflection in the hole during rock drilling;

4. During rock drilling, rocks fall from the wall or hole or encounter large cracks and caves;

5. Dust is not easy to discharge in areas with mud and rocks;

6. Negligence in operation. During long-term drilling stoppages, the rock powder was not blown off, and the drilling tool was not lifted, so that the impactor was sunk by the rock powder;

Treatment method: now the strength of the drill bit, the broken wings have basically been eradicated. In case of special circumstances, a piece of seamless pipe with a diameter similar to the hole diameter can be used. The pipe is filled with butter, asphalt, etc., and connected with the drill pipe to enter the bottom of the hole. Take out the broken wings at the bottom of the hole, and blow off the rock dust at the bottom of the hole before salvaging. In more serious cases, the drilling tool cannot be lifted up or put down, and the impactor does not sound. At this moment, it is only necessary to add torque or use auxiliary tools to assist in raising the drilling tool to reverse the drilling tool, and then raise the drilling tool while supplying air until the fault is resolved. When drilling rock from the beginning, first apply a little pressure, then give a little pressure, and then gradually increase the propulsion until the normal working pressure.
