1. Preparation before operation

Personnel Qualifications:

Operators must undergo special technical and related training and obtain corresponding qualification certificates before they can take up the job.

Equipment inspection:

Check whether all components of the drill rig are intact, including drill bits, drill rods, mud pumps, drill rig chassis, etc. to ensure that there is no damage.

Check electrical equipment, such as motors, cables, controllers, etc. to ensure normal operation.

Check the lubrication system to ensure sufficient lubricating oil and ensure normal lubrication of all components of the drilling rig.

Check the mud circulation system to ensure that the mud is clean and the flow is stable.

Personal Protection:

Wear personal protective equipment, such as hard helmets, protective glasses, dust masks, anti-slip shoes and protective clothing.

Check protective facilities, such as protective covers, warning signs, etc., to ensure they are intact.

2. Things to note during operation

Drilling rig installation and drilling:

Ensure that the drill rig is placed smoothly and the drill tools are arranged neatly according to classification.

Before drilling, find out whether underground pipelines are passing near the drilling hole, especially cables, optical cables, water supply pipes, etc., to avoid damaging underground facilities.

Operating specifications:

When operating the drill rig, you must concentrate and strictly prohibit operating, fighting or joking after drinking.

According to the geological conditions and drilling depth, the drilling pressure and rotation speed are reasonably selected and even feeding is carried out.

When drilling at geological unevenness or rock formation junctions, the drilling pressure and rotation speed should be reduced to slow down the feeding speed.

Drill Pipe and Drill Bit Management:

The connection between the drill pipe and the drill bit should be checked frequently to avoid loosening and falling off and injuring people.

When adding drill rods, check whether the sealing ring is intact and clean the connections. The connecting bolts must be tightened evenly to ensure the sealing of the connection.

Mud circulation and slag discharge:

Keep the mud circulation smooth and avoid the phenomenon of slurry.

Regularly clean the rock chips and impurities in the mud circulation system to keep the drilling unobstructed.

Emergency handling:

In an emergency, the operator should stop the operation immediately and take corresponding measures.

In case of fire, electric shock or other accidents, the power should be cut off immediately, fire extinguishers and other fire-fighting equipment should be used to extinguish the fire, and call the alarm for help.

3. Things to note after homework

Equipment cleaning and maintenance:

After drilling, clean the rig's surface sludge in time and apply lubricating grease.

Regularly check the wear of each component of the drill rig and replace the seriously worn parts in time.

Recording and analysis:

Record data during the drilling process, including depth, rock formation type, etc., for easy subsequent analysis.

Summarize and analyze the problems that arise during the operation process and propose improvement measures.

To sum up, when using a geological exploration drill rig, you need to pay attention to many aspects such as pre-operation preparation, operating process specifications, and post-operation cleaning and maintenance. By strictly following operating procedures and precautions, it is possible to ensure that the geological exploration drill rig works in a stable state.
