Some additional details related to using a wireline drill rod for rock coring in the mining industry:

1. Wireline Drill Rod Design:

   • Material Selection: Wireline drill rods are typically made of high-strength alloy steel to withstand the stresses and torque experienced during drilling operations. The choice of material depends on factors such as drilling depth, rock hardness, and environmental conditions.
   • Rod Configuration: Wireline drill rods are typically designed with a flush-joint configuration, where the outer diameter of the rod is consistent along its length. This design allows for smooth passage of the core barrel and minimizes the risk of getting stuck in the borehole.
   • Thread Types: Various thread types are used for wireline drill rods, such as API threads or proprietary designs. The thread type should match the core barrel and overshot assembly to ensure compatibility and secure connections.

2. Wireline Winch and Hoisting System:

   • Wireline winch: A wireline winch is used to lower and retrieve the drill string and core barrel assembly. It is equipped with a wireline cable that provides the necessary strength and flexibility for safe and efficient drilling operations.
   • Hoisting System: The wireline winch is typically mounted on a hoisting system, which may consist of a mast, derrick, or crane. The hoisting system provides the necessary support and lifting capacity to handle the drill string and core barrel during wireline coring.

3. Core Barrel Assembly:

   • Inner Tube: The core barrel assembly consists of an inner tube, which is designed to contain and protect the core sample during drilling. The inner tube can be split or non-split, depending on the specific requirements of the project.
   • Core Lifter: The core lifter is an essential component of the core barrel assembly. It is designed to hold the core sample in place during retrieval and prevent it from falling back into the borehole. The core lifter is released when the core barrel is lifted to the surface, allowing for easy extraction of the core sample.
   • Overshot Assembly: The overshot assembly is used to engage with the core barrel and retrieve the core sample to the surface. It consists of a latch mechanism that securely attaches to the core barrel, allowing for controlled retrieval without pulling up the entire drill string.

4. Wireline Deployment and Retrieval:

   • Deployment Process: The drill rod sections are assembled on the surface and lowered into the borehole using the wireline winch. The core barrel assembly is attached to the bottom of the drill rod string, and drilling begins once the coring depth is reached.
   • Retrieval Process: When the coring operation is complete at a particular depth, the wireline winch is used to retrieve the core barrel assembly to the surface. The overshot assembly engages with the core barrel, allowing for controlled retrieval of the core sample without disassembling the entire drill string.

5. Core Sample Handling and Storage:

   • Core Logging: After the core sample is retrieved, it undergoes a process called core logging. This involves visual examination and description of the core, including features such as color, texture, mineralogy, fractures, and any other relevant characteristics. Core logging provides valuable information for geological interpretation and further analysis.
   • Core Sample Preservation: Core samples are typically wrapped in plastic or placed in sealed bags to prevent moisture loss and contamination. It is important to handle the core samples carefully to maintain their integrity and prevent any damage during transportation and storage.
   • Core Sample Storage: Core samples are stored in a designated core storage facility, where they are organized and cataloged for future reference. Proper storage conditions, including temperature and humidity control, are maintained to preserve the physical and chemical properties of the core samples.

Wireline coring using a drill rod is a widely used technique in the mining industry for obtaining accurate and representative core samples. The method offers several advantages, including increased efficiency, reduced sample loss, and deeper penetration capabilities. By following industry best practices and equipment recommendations, mining professionals can gather valuable geological and geotechnical data to support mining exploration, resource evaluation, and mine planning activities.

FAQ:

Q1: How do you handle drill pipe protectors?
A: Slide heavy tapered protectors onto vulnerable connections near the bit and change periodically as they wear.

Q2: How do you break a rod connection?
A: Use a power spinner or jar to apply a sudden force in the opposite direction of makeup to break the friction between the threaded surfaces.

Q3: How do you trip in heavy collars or tools?
A: Attach lifting subs, slings or bails and pick up with a derrick man or knuckle boom truck to carefully lower heavy bottomhole assembly components.

Q4: How do you inspect rods for wear or damage?
A: Visually check for cracks, thin spots, galling or thread and coupling wear periodically or before running new pipe.

Q5: How do you safely rack and stack drill pipe?
A: Use handling equipment and lay rods on wood or pipe ramps in an organized manner with tags or markers and adequately spaced for inspection and repairs.
