The Crawler-Type Hydraulic Drilling Jumbo for Coal Mines is a high-performance mechanized drilling rig designed for rapid roadway development in underground coal mining operations. Equipped with a crawler chassis and hydraulic drilling system, it offers excellent mobility, powerful drilling capability, and enhanced adaptability in complex geological conditions, especially in soft or fractured coal seams.

Key Features:

• Crawler-Mounted Mobility
  The self-propelled crawler chassis enables stable movement across uneven underground terrain, offering superior traction and maneuverability in tight or inclined tunnels without the need for rail systems.

• Powerful Hydraulic Drilling System
  Featuring advanced hydraulic rock drills, the jumbo is capable of drilling precise blast holes or bolt holes efficiently, with high penetration rates and excellent reliability.

• Multi-Arm or Single-Arm Configurations
  Available in both single and dual-boom models, allowing simultaneous drilling in multiple positions to accelerate tunnel advance and improve operational flexibility.

• Robust and Compact Design
  Built to operate in low-seam or narrow-profile environments, with a reinforced frame, low center of gravity, and ergonomic layout that enhance durability and operator convenience.

• Advanced Safety and Control Systems
  Includes features such as overload protection, automatic water flushing, dust suppression, and centralized control panels, with optional remote-control functions to increase operator safety.

Application Fields:

• Roadway excavation and tunneling in underground coal mines

• Drilling operations in main entries, crosscuts, and inclined seams

• Mechanized tunneling in soft or fractured coal formations

• Integration with blasting or bolt-installation workflows

With its strong adaptability, efficient drilling performance, and intelligent control systems, the Crawler-Type Hydraulic Drilling Jumbo for Coal Mines is an essential solution for modern coal mine infrastructure development. It significantly reduces manual labor, improves advance rates, and ensures safe, continuous tunneling operations even in demanding underground environments.
