Storage and safe use of mining drill pipes

Mining drill pipe, made of seamless steel with a wall thickness of 7-12mm, consists of two parts: the drill pipe body and the drill pipe joint. There are two connection methods for the pipe body and joint: fine thread connection, where male threads on the pipe connect to female threads on the joint, forming a fine-buckle drill pipe, and friction welding, where the body and joint are butt-welded, forming a butt-welded drill pipe.

The mining drill pipe, featuring a threaded tail, connects surface drilling rig equipment to the bottom-hole device. Its primary function is to deliver drilling mud to the drill bit and assist in raising, lowering, or rotating the bottom-hole device during oil and gas extraction. It is reusable throughout the extraction process.

Mining drill pipes, essential for mining machinery, are made up of drill bits, rods, wrenches, installation tubes, bolts, and locks. The drill bit, made from wear-resistant, pressure-resistant materials, is key to performance, while other components ensure proper tightening and stability. Correct storage and usage of the drill pipe can extend its service life and reduce failure risks, making it a crucial component in rotary drilling rigs.

Mining Drill Pipe Storage Guidelines

When placing the drill pipe after disassembly, use sleepers to level the storage area, preventing collisions and local deformation. This also helps keep debris from entering between the layers, avoiding jamming issues.

For long-term storage, ensure the inner teeth section is thoroughly cleaned to remove mud, slag, and other debris. This prevents solidification that could interfere with future use.

After installing the drill rod, rotate it forward and backward several times before use. This helps clear out any debris accumulated during idleness, preventing jamming during operation.

Safe Use of Mining Drill Pipes

After the rig has been operating for a while, inspect the supporting cylinders for leakage to prevent the mast from tilting in any direction, which could result in an oblique hole.

Ensure that the drill pipe and drill bit are securely connected to avoid the drill pin or bit from falling to the bottom of the hole.

Track the position of the drill bit after each section of the drill pipe is extended, and monitor the status of the drill pipe’s extension at various depths.

If the drill pipe frequently jams during use, stop and follow proper disassembly procedures for inspection and maintenance.

Regular maintenance of the drill pipe is essential. Establish a maintenance schedule and regularly perform rust and dust prevention treatments.

During drilling, ensure the drill pipe is tightly connected when ventilating or watering. If the drill pipe includes seals, such as O-rings, inspect them for damage or corrosion and replace them promptly. After drilling, clean and maintain the seals.

Drill pipes with threaded connections should be tightened manually to ensure a proper fit. Avoid using the drilling rig for tightening to prevent damage.

In acidic or alkaline environments, monitor the drill pipe for corrosion. After drilling, clean the pipe's surface with water to remove any corrosion.

Store drill pipes in a dry location with multiple points of support and maintain them regularly if stored for extended periods.

Avoid using drill pipes as supports for heavy loads or stacking them randomly under gravel or coal piles.

After maintenance and rust/dust removal, cover the drill pipe with a protective cap or seal it to keep it in optimal condition for future use.
