deep drilling rig for coal mines with advanced safety

Introduction of Deep Drilling Rig

The deep drilling rig for coal mines is a highly efficient drilling equipment specially designed for safe underground coal mine operations. Featuring a crawler chassis, it is capable of handling various drilling tasks such as water detection, gas exploration, fault investigation, roof management, and water injection. The machine offers 360° vertical rotation, -90° to +90° pitch adjustment, and the drill arm supports a vertical lift of 520mm, making it adaptable to complex and variable underground environments. Whether carrying out intensive drilling in soft rock or coal seams or performing drilling in other special scenarios, this equipment delivers excellent performance.

Features of Deep Drilling Rig

• High safety performance, significantly reduces workers’ physical labor, and is suitable for a variety of roadway sections and slopes.
• Fully hydraulic drive, compact structure, flexible operation, crawler travel for easy movement and relocation, greatly improving work efficiency.
• Powerful torque on the power head, long stroke, fast drilling speed, significantly enhancing construction efficiency.
• Hydraulic system is equipped with a rapid propulsion function and an auxiliary rod handling device, which increases rod handling speed and further reduces labor intensity.
• Uses a variable hydraulic system—high speed when unloaded, automatically increases torque under load—ensuring smooth and efficient drilling, suitable for complex geological conditions.

Application Fields

The deep drilling rig for coal mines is widely used in underground mining faces, especially for intensive drilling with outburst prevention requirements. In addition, it is suitable for water, gas, and fault detection, as well as roadway water injection, roof management, and other purposes, meeting the diverse needs of coal mines and related geological engineering projects.
