Les barres de forage, ou drill rods en anglais, jouent un rôle crucial dans l'industrie de l'exploration minière et pétrolière. Elles constituent un élément essentiel des équipements de forage, permettant de percer le sol et d'atteindre les profondeurs nécessaires pour explorer les ressources naturelles. Dans cet article, nous examinerons les différents types de barres de forage, leurs matériaux, ainsi que leur importance et leur application dans l'industrie.

1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

The main components of submarine hammer drilling equipment include the drill rig, hammer, drill pipes, and the drill bit. The drill rig is often mounted on a surface vessel or a floating platform and is designed to support the excessive weight and dynamic forces encountered during drilling operations.

1. Mining Industry In mining operations, heavy slurry pumps play a critical role in the extraction and processing of minerals. They are used to transport slurries containing ores, which can be heavily loaded with solids. These pumps facilitate the movement of material from the mining site to processing plants, significantly enhancing operational efficiency while reducing the risk of equipment damage due to the abrasive nature of mine slurries.

Additionally, submarine hammer drilling is a versatile technique, suitable for various applications, including the installation of underwater pipelines, foundations for offshore structures, and the recovery of geological samples for research and analysis. This adaptability makes it an essential tool in the fields of marine engineering, environmental research, and resource extraction.

2. Marine Construction When constructing offshore platforms, bridges, or wind farms, the stability of foundations is paramount. Hammer drilling provides a reliable method to secure pilings and conduct deep foundation work, ensuring that structures can withstand harsh marine conditions.
