The Crawler-Type Full Hydraulic Directional Drilling Rig for Coal Mines

The crawler-type full hydraulic directional drilling rig for coal mines is a high-performance drilling device specifically designed for complex underground mining environments. This rig is powered by an electric motor, which drives the hydraulic pump and hydraulic motor, enabling the crawler chassis to move independently and ensuring efficient operation of the drilling tools. It is equipped with a mining explosion-proof intrinsically safe while-drilling measurement system, including a dedicated computer, measurement probe, data processor, and intrinsically safe keyboard, with an optional data storage unit for data transfer and monitoring during drilling. The equipment is capable of multi-angle drilling in the range of -15° to +15°, meeting all-around drilling needs.

Main Features of the Crawler-Type Full Hydraulic Directional Drilling Rig for Coal Mines

• Compact structure with a rational overall layout, occupying minimal space and facilitating underground transport and relocation.
• Full hydraulic control system for simple, flexible operation and rapid response, improving work efficiency.
• Crawler chassis for easy movement, adaptable to various tunnels and working conditions.
• Large torque and long stroke of the power head, suitable for high-efficiency drilling over long distances and in complex strata.
• Equipped with a rapid-advance hydraulic system, significantly reducing the time required for loading and unloading drill rods and improving operational continuity.
• Variable hydraulic system automatically adjusts speed and torque according to load, ensuring smoother and more rational drilling processes.
• While-drilling measurement device enables precise control of borehole direction, ensuring drilling quality and safety.
• Multi-functional expansion capability, compatible with various drilling tools for water exploration, gas detection, reaming, and other operations.
• Highly automated design, effectively reducing workers’ physical labor and enhancing underground operation safety.

Application Fields

The crawler-type full hydraulic directional drilling rig for coal mines is widely used in intensive drilling projects such as water exploration, gas detection, fault detection, roof cutting, and water injection in underground coal mines. It is especially suitable for dense drilling in soft rock or coal seams where outburst prevention is required at the excavation face. It can also be used for drilling in various complex strata, making it an essential piece of equipment for mine safety protection, geological exploration, and disaster management.
