What Details Need To Be Noted In The Transportation And Storage Of Coring Drilling Tools To Avoid Damage?

2025-12-05

Protective measures must be taken during the transportation of coring drilling tools. Before loading, the surface of the tools should be wrapped with wear-resistant canvas to prevent scratches caused by friction with metal parts of the carriage due to jolts during transportation. At the same time, the tools should be placed in layers, with wooden partitions between each layer to avoid mutual collision of the tools. In particular, precision parts such as bits need to be placed in special protective boxes separately. There are clear requirements for the selection of storage sites. Firstly, the site must be flat to prevent the tools from rolling due to the inclination of the ground. Secondly, a sunshade should be built at the site to prevent the surface coating of the tools from aging due to long-term direct sunlight. If the storage environment has high humidity, desiccants should be placed in the site to reduce the erosion of moisture in the air on the metal parts of the tools. In addition, regular inspections during the storage of the tools should not be ignored. Every week, it is necessary to check whether the connecting threads of the tools are rusted. If slight rust is found, it should be wiped clean with a special rust remover. At the same time, check whether the cutting edges of the bits are i...

During Geological Exploration, How Does The Coring Drilling Tool Deal With Complex Formation Conditions?

2025-12-05

In geological exploration operations, the diversity of formation conditions often poses challenges to the use of drilling tools. When facing loose sandy soil layers, the anti-collapse design of the coring drilling tool comes into play. The special coating on the outer wall of the tool can reduce the adhesion of soil particles, while the internal circulation channel continuously delivers wall protection fluid to prevent the borehole wall from collapsing due to loss of support. When encountering hard quartz rock formations, the bit material of the coring drilling tool becomes crucial. The bits of such tools are mostly made of high-strength alloys, which can gradually break rocks during rotational drilling. Moreover, the tooth shape of the bits is optimized to disperse the pressure during drilling, avoiding tool failure caused by excessive local wear. When there are faults or fractures in the operation area, the flexible connection parts of the coring drilling tool show their advantages. The connecting joints between tools can adjust the angle within a certain range to adapt to slight deviations of the formation, reducing tool jamming caused by faults and ensuring that exploration operations can continue to advance and obtain complete geological samples....

From Which Aspects Can Maintenance Of Coring Drill Rods Extend Their Service Life?

2025-12-05

Daily cleaning is a basic step in the maintenance of Coring Drill Rods. After each operation, the surface of the rod will be covered with impurities such as rock slag and mud. If these impurities are not cleaned in time, they may corrode the rod's surface during storage—especially in humid environments, where the corrosion speed will accelerate. Workers usually use high-pressure water guns to rinse the surface of the Coring Drill Rod, then wipe it dry with a dry cloth to ensure no residual impurities are left on the surface. Regular inspection of the key parts of the Coring Drill Rod is also necessary. Parts like the rod's joints and threads bear more force during use and are prone to wear or deformation. During inspection, workers will check if there is thread slipping at the threads and if there are cracks at the joints. Once these problems are found, they will repair or replace the parts in time to avoid more serious failures in subsequent operations. Proper storage also helps extend the service life of Coring Drill Rods. The storage site needs to be dry and well-ventilated, avoiding direct sunlight and rain. When storing, the Coring Drill Rods should be arranged neatly to prevent damage from mutual collision. At the same time, it is not allowed to stack the rods on uneven ground,...

In Mine Excavation, How Does The Coring Drill Rod Adapt To Operational Requirements At Different Depths?

2025-12-05

In mine excavation scenarios, operational requirements at different depths bring varying demands for Coring Drill Rods. During shallow-depth excavation, the formation structure is relatively simple. The main task of the Coring Drill Rod is to handle conventional rock fragmentation, and at this stage, the stability of the rod's connections becomes a key factor. Workers will carefully check the fit of the Coring Drill Rod joints to ensure that no loose connections affect the operation progress when the rod rotates at high speed for drilling. As the operation depth increases, the formation pressure gradually rises, and the hardness of the rock may also increase. At this point, the material characteristics of the Coring Drill Rod start to play a role. Rods with a certain level of toughness and strength can withstand greater pressure while reducing the possibility of breakage caused by hard rocks. Meanwhile, in deep-depth operations, the fatigue resistance of the Coring Drill Rod must be taken into account. Long-term drilling operations keep the rod under continuous stress, and rods with good fatigue resistance can extend the service cycle and reduce the frequency of replacements. In addition, the slag discharge requirements at different depths also impact the use of Coring Drill Rods. For shallow-...
