Audited Supplier some additional details to consider when using a diamond reamer (reaming shell) in coring drilling within the mining industry:
Core Recovery: The primary objective of coring drilling is to recover intact core samples for geological analysis. The design and performance of the reaming shell can significantly impact core recovery. It should facilitate efficient cutting and prevent excessive core loss or damage during the drilling process.
Hole Deviation: Hole deviation refers to the deviation of the borehole from its intended path. It can occur due to various factors, including the drilling equipment and geological conditions. The selection of the appropriate reaming shell can help minimize hole deviation and maintain the desired trajectory.
Reaming Shell Alignment: Proper alignment of the reaming shell is essential to ensure accurate and straight drilling. Misalignment can lead to deviations and affect the quality of the core samples obtained. Regularly check and adjust the alignment of the reaming shell to maintain drilling accuracy.
Drilling Fluid Properties: The properties of the drilling fluid, such as viscosity, density, and pH, can influence the performance of the diamond reamer. The fluid should be properly formulated to provide adequate lubrication, cooling, and debris removal while minimizing any adverse effects on the diamonds.
Cutting Efficiency: The cutting efficiency of the reaming shell depends on factors such as diamond quality, design, and drilling parameters. It is important to monitor the cutting performance during drilling operations. If the cutting efficiency decreases significantly, it may indicate a need for reamer replacement or adjustment of drilling parameters.
Downhole Conditions: The downhole conditions encountered during coring drilling can vary significantly. Factors such as rock hardness, abrasiveness, and presence of water or other fluids can impact the performance of the reaming shell. Adjust drilling parameters and equipment as needed to adapt to the specific downhole conditions.
Safety Precautions: Always prioritize safety during coring drilling operations. Follow all relevant safety guidelines and procedures, including the use of personal protective equipment (PPE) and adherence to local regulations. Regularly inspect the drilling equipment, including the reaming shell, for any signs of wear or damage that could pose safety risks.
Environmental Considerations: Be mindful of environmental considerations when using a diamond reamer. Proper containment and disposal of drilling fluids and cuttings should be implemented to prevent contamination of soil, water sources, or surrounding ecosystems. Comply with environmental regulations and best practices to minimize the ecological impact of drilling activities.
Remember, every drilling operation is unique, and it's essential to adapt the usage of the diamond reamer to the specific geological conditions, equipment, and objectives of the mining project. Regular monitoring, maintenance, and adjustment of drilling parameters will help optimize the performance and longevity of the reaming shell while ensuring successful coring drilling outcomes.
