1. The geological drill pipe needs to be regularly maintained and maintained to determine the maintenance cycle, and regular anti-rust and dust-proof treatment.
2. The use of geological drill pipe should be within the rated drilling distance of the drilling rig, and the matching drill pipe should be used according to the technical parameters and model of the drilling distance.
3. The geological drill pipe is friction welded with the special geological drill pipe for mining geology and its matching joint, so it has good followability and high tensile strength, and can be used in conventional drilling and gas discharge. When working in hard rock layers, coal seams or other special environments, the drilling depth should be determined according to the actual material, physical properties and parameters of the drill pipe.
4. When the geological drill pipe is used together with the drill bit, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the conditions of the drilling rig and the drill pipe should always be paid attention to during the drilling process. In case of stuck drill, sudden death, etc., the drilling should be stopped immediately or drilled back slowly to ensure that the drill pipe is not bent and flat.
5. When the geological drill pipe is ventilated or watered, it should be determined that the drill pipe is tightly connected when drilling. When the drill pipe has seals, such as O-rings, pay attention to the use of the seals, and replace the seals in time when damage or corrosion occurs. After drilling is completed, maintenance and cleaning of the seals are performed.
6. When the geological drill pipe is drilled, it should be manually tightened to ensure a tight fit (thread type), and the drilling rig should not be used to drill directly to prevent damage to the drill pipe.
