  • 产品描述
  • Drill Rods, namely mining drill rods, are the core supporting components of the mining rock drilling and probing system. They work in conjunction with rock drills, drill bits, impacters, etc., and are mainly used to transmit impact energy, torque, convey compressed air / cooling water, and remove debris. They are widely applicable in various scenarios such as open-pit mining, underground tunnel excavation, blasting holes, water exploration / gas extraction, slope anchoring, geological drilling, etc. They are the key load-bearing and transmission components that connect the drilling machine with the drill bit.

    Product Classification

    1. Top Hammer Drill Rods

    Applicable to: top hammer rock drills, underground mining, tunnel excavation, shallow-hole blasting holes
    Structure: Integral quenched alloy steel, both ends with precise threads (R/T standard threads)
    Advantages: High torsional resistance, impact resistance, less prone to bending and breaking, high alignment accuracy, good drilling straightness
    Specifications: Common length 0.6m - 6.0m, universal mining threads R25/R32/T38/T45/T51
    2. DTH Drill Rods

    Applicable to: DTH impacters + DTH drill bits, deep-hole blasting in open-pit mines, large-scale quarrying sites
    Structure: Thickened tube body + friction welding / overall forging process, direct ventilation holes
    Advantages: Stable high-pressure ventilation, smooth debris removal, no deformation during deep-hole drilling, wear-resistant and corrosion-resistant
    Specifications: Outer diameters 76mm/89mm/102mm, lengths 1.5m - 6m
    3. Hexagonal Drill Rods / Hollow Hexagonal Drill Rods
    Applicable to: small handheld, pneumatic leg rock drills, mining small-section tunnels, quarry operations
    Characteristics: Hexagonal shape to prevent slipping, hollow for water / air passage, lightweight, easy to disassemble and assemble
    Application: Short-distance shallow-hole drilling, high cost-effectiveness, extremely versatile
    4. Coal Electric Drill Rods / Geological Drill Rods
    Used mainly in coal mines: gas extraction, water exploration, gas exploration, coal seam drilling
    Types: Smooth rods, ribbed rods, wear-resistant and corrosion-resistant, suitable for drilling in soft rock layers
    5. Extended Drill Rods / Directional Drill Rods
    Used for deep-hole drilling, directional excavation, high-strength resistance to lateral load, meeting the requirements for ultra-long-distance hole formation

    Core Materials and Manufacturing Processes

    ◆ High-quality alloy structural steel
    Select high-strength chromium-molybdenum alloy steel as the base material, overall forging + overall heat treatment (quenching and tempering), high tensile strength, impact resistance, torsional resistance, and fatigue resistance.
    Precision thread processing
    Threads are processed by precise CNC machining, surface strengthening treatment, tight engagement, smooth disassembly, and no slippage, detachment, or air and water leakage.
    Surface strengthening treatment
    Anti-rust and wear-resistant coating on the outer wall, suitable for harsh environments in humid, dusty, and highly corrosive mines, extending service life.
    Integrated hollow molding
    Smooth inner walls, low resistance for ventilation / water passage, high debris removal efficiency, reducing stuck drill, blocked holes.

    Core Product Advantages

    ◆ High strength and durability
    Impact resistance, bending resistance, torsional cracking resistance, less prone to deformation under heavy load operation, reducing the risk of fracture and machine shutdown.
    Sealed transmission stability
    Precise thread connection, strong sealing, low wind pressure / water pressure loss, stable rock-breaking efficiency.
    High adaptability and versatility
    Complete series of standard specifications, compatible with mainstream brands of drilling machines, rock drills, impacters, drill bits, etc., customizable in size, thread, and length as needed.
    Cost reduction and efficiency improvement
    Long service life, low failure rate, reducing the frequency of parts replacement and maintenance costs, improving the overall drilling construction efficiency in mines.
    Adaptability to harsh environments
    Dust-proof, rust-proof, resistant to high and low temperatures, suitable for hard rock, abrasive rock layers, and humid underground conditions.

    Main Application Domains

    ◆ Metal mines / non-metal mines, open-pit & underground blasting holes

    ◆ Mine tunnel excavation, water exploration, gas extraction, support and anchoring holes

    ◆ Tunnels, water conservancy, infrastructure rock drilling projects

    ◆ Quarry sites, stone material mining, slope reinforcement drilling. Geological exploration, auxiliary drilling for geological sampling in mines
