Rotary rig rock drilling bucket, as an efficient tool for earth and rock engineering, is widely applied in the construction of foundation works. Rock drilling bucket is an important accessory for rotary drill, mainly used to mine soil, sand, stones and other materials. The detailed procedure for using the bucket on a rotary drill attached below for reference:

 

 

Preparations

Inspection of equipment: Before starting work, it is necessary to conduct a complete inspection of the rotary drilling rig, including but not limited to the engine, hydraulic system and operation system, to ensure that all components are working normally and not damaged.
Installation of drilling bucket: Select the appropriate type according to the construction needs, install it correctly on the bottom of the drill pipe to ensure the connection is firm and there is no movement.

 

 

Starting the equipment

Starting the rotary drilling rig: Start the equipment following the operating procedure, and after the engine is running stably, lower the drill pipe into the ground.
Position Adjustment: According to the construction design, adjust the position of the rotary drill to align with the excavation point using the controls in the cab.

 

 

Excavation Operation

Drilling: Operating the rotary drill control system, have the drill pipe with the drilling bucket slowly lowered into the soil layer.
Excavation with Rotation: Once the drill bit touches the ground, activate the rotation mechanism to rotate the dredger and at the same time press the drill pipe to excavate. The helical blades of the drilling bucket will pick up the soil or stones and put them into the basket.
Ascending: When the drilling bucket is full of material, stop the rotation and raise the drill pipe to lift the drilling bucket from the ground.

 

 

Unloading Materials

Opening the drilling bucket Door: Once it has been raised to a safe height above the ground, open the door using the control device to unload the materials.
Closing the drilling bucket door: After confirming that the materials have been completely unloaded, close the door to prepare for the next excavation.

 

Repeating the operation According to the construction needs, repeat the above steps until the excavation task is finished. Throughout the process, the operator must pay continuous attention to the operating status of the equipment and detect and solve any problems that may arise in a timely manner.

 

In summary, the procedure for using the rotary drilling bucket is rigorous and efficient, and the operator must possess professional knowledge and skills and strictly follow the safety operation rules to ensure the successful execution of the construction and the safe operation of the equipment.

 

 

A "rotary drill" in drilling refers to a type of drilling machine that uses a rotating drill bit to penetrate soil, rock, or other materials. This type of drilling is widely used in various industries, including construction, mining, and oil and gas exploration. The main components and process of a rotary drilling rig are as follows:

 

Drill Bit: The cutting tool at the end of the drill string that cuts into the material.
Drill Pipe: A series of connected metal pipes that transmit the rotational force from the rig to the drill bit.
Drill Collars: Heavier, thicker pipes below the drill pipe that provide weight and stability to the drill bit.
Rotary Table: The component of the rig that rotates the drill pipe and drill bit.
Kelly: A square or hexagonal pipe that passes through the rotary table and transmits the torque from the table to the drill string.
Drawworks: The hoisting mechanism that raises and lowers the drill string.
Mud Pump: A pump that circulates drilling mud down the hole and back up to the surface, which helps in cooling the bit, carrying the cuttings to the surface, and maintaining pressure in the wellbore.
Swivel: A device that allows the drill string to rotate while maintaining a connection to the mud circulation system.

 

Here is how a rotary drilling rig typically operates:

 

The rig is set up over the intended drilling location.
The drill bit is attached to the bottom of the drill string, which is connected to the rig.
The rotary table or top drive (a motor at the top of the rig) rotates the drill string, causing the drill bit to rotate and bore into the ground.
Drilling mud is pumped down the center of the drill string and out through the drill bit. The mud flushes cuttings out of the hole and helps to stabilize the wellbore.

 

As drilling progresses, additional sections of drill pipe are added to extend the drill string.
Once the desired depth is reached, or the hole is completed, the drill string is removed from the hole, and any necessary casing or lining can be installed.
Rotary drilling is efficient and can be used in a wide variety of geological conditions, making it a versatile and widely used method in the drilling industry.

 

 

Rotary drilling and percussion drilling are two distinct methods used in the drilling industry to create holes in the ground. Here are the main differences between the two techniques:

 

Rotary Drilling:

Mechanism: Rotary drilling involves rotating the drill bit at the end of the drill string to cut through the ground materials. The rotation of the bit breaks up the material, which is then removed by the drilling fluid (mud) or by mechanical means.

Bit Type: The drill bits used in rotary drilling are typically milled-tooth or polycrystalline diamond compact (PDC) bits that have cutting edges designed to grind and crush the rock.

Application: Rotary drilling is commonly used in oil and gas exploration, construction, and water well drilling. It is effective in a wide range of soil and rock types.

Speed: Rotary drilling is generally faster than percussion drilling, especially in harder rock formations, because it continuously removes material as the bit rotates.

Accuracy: This method can provide more precise and straight holes due to the continuous rotation and the ability to control the direction of the bit.

Drilling Fluid: Rotary drilling usually requires the use of drilling mud to lubricate the bit, carry away cuttings, and maintain wellbore stability.

 

Percussion Drilling (also known as Impact Drilling):

Mechanism: Percussion drilling involves raising and dropping a heavy drilling tool (such as a drill bit or a hammer) onto the bottom of the hole to break up the material through repeated impacts.

Bit Type: The drill bits used in percussion drilling are often blunt and heavy, designed to deliver impact force rather than to cut through the material.

Application: Percussion drilling is more commonly used in softer formations like clay, loose sand, or shallow drilling operations. It is less effective in hard rock formations.

Speed: Percussion drilling can be slower than rotary drilling, especially in hard rock, because it relies on the force of impact to break the material rather than continuous cutting.

Accuracy: The holes created by percussion drilling may not be as straight or precise as those made by rotary drilling, due to the nature of the impact action.

Drilling Fluid: Percussion drilling may not always require drilling mud, especially in shallow or less stable formations, but it can still be used to flush out debris.

 

In summary, the primary difference between rotary and percussion drilling lies in the way the drilling action is performed: rotary drilling cuts the material through continuous rotation, while percussion drilling breaks the material through repeated impacts. The choice between the two methods depends on the geological conditions, the desired depth and diameter of the hole, and the efficiency required for the specific drilling operation.

 

 

The depth that a rotary drilling rig can reach depends on several factors, including the design and capabilities of the rig, the geological conditions, and the purpose of the drilling operation. Here are some general guidelines:

 

Shallow Drilling: For shallow drilling operations, such as for building foundations or water wells, rotary drilling rigs can typically drill to depths of a few tens of meters, often up to about 150 meters (492 feet).

Medium-Depth Drilling: In intermediate-depth applications, such as some mining operations or deeper water wells, rigs can drill to depths ranging from about 150 to 600 meters (492 to 1,969 feet).

Deep Drilling: For oil and gas exploration or certain types of mining, rotary drilling rigs are capable of drilling to much greater depths, often reaching 1,000 to 5,000 meters (3,281 to 16,404 feet) or more. Some advanced rigs can even exceed 10,000 meters (32,808 feet) in depth.

Ultra-Deep Drilling: In specialized cases, such as ultra-deep oil and gas exploration, certain rigs have been designed to drill to extraordinary depths, surpassing 12,000 meters (39,370 feet). However, such depths are rare and require highly specialized equipment and techniques.

The following factors limit the drilling depth:

Rig Capacity: The size and power of the rig, including the strength of the hoisting system, the torque of the rotary table or top drive, and the pump capacity for circulating drilling mud, all limit how deep a rig can drill.

Drill String Design: The length and strength of the drill string, including the drill pipe and drill collars, must be sufficient to withstand the forces encountered at greater depths.

Geological Conditions: The type of rock and soil, as well as the presence of groundwater, natural gases, or high temperatures and pressures, can affect the drilling process and the maximum achievable depth.

Economic Considerations: The cost of drilling increases significantly with depth, so economic factors often determine the practical limit for drilling operations.

Technical Limitations: Current technology has its limits, and drilling beyond certain depths may require new innovations in equipment design and drilling techniques.

 

It's important to note that as drilling depth increases, the challenges and costs associated with the operation also increase, making it a complex and resource-intensive endeavor.
