crawler deep hole drilling rig for underground coal mine

Deep Hole Drilling Rig for Coal Mines

The deep hole drilling rig for coal mines is an efficient drilling machine specially developed for complex underground mining environments. This equipment features a crawler-type chassis, enabling flexible movement in various terrains such as horizontal and inclined roadways. It supports 180-degree horizontal rotation, 700mm vertical lifting, and -20° to +45° pitch adjustment, allowing for multi-angle, all-direction drilling operations. It is widely used for intensive drilling projects in coal mines, including water exploration, gas detection, fault detection, roof cutting, and water injection. The rig is especially suitable for soft rock and coal seam environments with outburst prevention requirements, and is also capable of handling drilling tasks in various complex strata.

Main Features of the Deep Hole Drilling Rig for Coal Mines

• Compact structure and small size, making it easy to operate and relocate in narrow underground spaces.
• Full hydraulic control system provides convenient operation and quick response, greatly enhancing operational flexibility.
• Crawler chassis ensures stable and efficient movement, strong maneuverability, and adaptability to different working environments.
