What Are the Considerations for the Operation of Geological Core Drilling Rigs?

The geological core drilling rig is a crucial component of drilling operations, with the drill bit being a vital part of the rig. The performance and quality of the geological core rig are directly influenced by the drill bit. Proper usage of the drill bit during operations is essential for maximizing work efficiency and ensuring high-quality results. In the following sections, I will outline key precautions and considerations for using this equipment effectively during drilling operations.

1. Once the drill bit has penetrated the structure, it is essential to promptly replace the center drilling tool. First, clean the bottom of the hole, then use compressed air to blow away any residue. After this, slowly raise the drilling tool in the geological core drilling rig, ensuring that the lifting force is just sufficient to lift the drilling tool smoothly.

2. During the drilling process, it is crucial to closely monitor the status of the casing to stay informed about the specific conditions within the hole. Maintain the cleanliness of the hole as needed. Additionally, it is strictly prohibited to pull the drill bit up while it is still engaged in the drilling rig.

3. Occasionally, the bottom of the hole in the geological core drilling rig may accumulate excess rock debris, causing the rotary part of the eccentric shaft bit to become jammed. This can hinder the equipment's performance. To address this issue, transport compressed air to clean the hole again, allowing the DTH hammer to operate for a short period. Afterward, you can lift the center drilling tool once more.

The above points highlight important considerations for operating the geological core drilling rig. By adhering to these guidelines, we can ensure optimal equipment performance, extend its service life, and achieve greater benefits from its use.

Drilling Techniques and Methods

The choice of drilling technique can significantly affect the quality of core samples and the efficiency of the operation. Some common techniques include:

Diamond Core Drilling: This method uses diamond-tipped bits for precise drilling, producing high-quality samples ideal for geological analysis.

Rotary Drilling: Rotary drilling is a versatile method suitable for various materials and depths, making it a popular choice for many projects.

Auger Drilling: This technique is effective for shallow depths and softer materials, providing quick and cost-effective sampling.

Each technique has its advantages and limitations, so it’s essential to choose the right method based on site conditions and project goals.

Conclusion

The operation of geological core drilling rigs involves careful consideration of various factors, from site assessment and equipment selection to safety measures and post-drilling procedures. By addressing these considerations, operators can ensure a successful drilling operation that yields high-quality geological data.
