Common Fault Analysis and Troubleshooting Method of Anti-well Drilling Rig

① Check the steering of the motor. Check whether the filter element of the oil filter is blocked. If it is blocked, it needs to be replaced or cleaned. ③ Check whether the air in the auxiliary pump is discharged, pull out the hose at the oil outlet of the auxiliary pump, and turn the coupling by hand to discharge the air. ④ Check whether the auxiliary pump is unloaded internally, pull out the hose of the oil return port of the auxiliary pump to check the oil output. If the oil volume is too large, the auxiliary pump needs to be replaced or the oil distribution plate needs to be ground. ⑤ Check the combined operation valve, plug the unloading valve with a plug or replace a piece of valve. Check whether the relief valve spool is worn or blocked by pollutants, kerosene or gasoline can be used to clean the valve body or directly replace the new relief valve. ⑦ Check the level gauge to see if the oil tank is full.

Construction Method of Anti-shaft Drilling Rig for Ventilation Shaft

The excavation procedure of ventilation shaft is generally as follows: construction of anti-well drilling rig operation platform → construction of anti-well drilling rig foundation and circulating water tank → installation of clean water cylinder with small submersible pump as cooling circulating water for main engine → installation of anti-well drilling rig and commissioning → guide hole construction → reaming construction → removal of drilling rig → ventilation well protection construction.

Construction Procedure of Anti-well Drilling Rig

Foundation pouring (including circulating water tank in the first phase) → anti-well drilling rig mobilization and installation (including high-pressure well flushing pump), initial positioning of survey, pilot hole construction → drill bit exposed at predetermined depth (if not exposed, expansion and excavation are found) → reaming bit installation platform construction → reaming bit lifting → reaming bit installation → installation platform withdrawal → reaming bit removal → reaming bit removal → reaming bit removal → reverse well drilling rig removal.

Understanding and Application of Drilling Technology of Anti-well Drilling Rig

Chamber drilling: according to the inclination of the well and the type of drilling rig to excavate the chamber and pouring chamber floor. The floor of the chamber shall be flat. When pouring the floor, anchor bolt installation holes (secondary pouring) shall be reserved for the installation of the drilling machine. In order to discharge the rock slag discharged when the pilot hole is drilled, a 300 × 300mm (long) drainage ditch shall be poured when pouring the foundation. The ditch shall have a certain slope to facilitate slag discharge. If there is no ditch in the roadway, a water nest must be dug to install a submersible pump.
