CMO2-400\/55 (K) Coal Mine Roof-Cutting Drill Rig<\/a>: High-Efficiency Pre-Splitting & Bolting<\/strong><\/h2>\n

The Coal Mine Roof-Cutting Drill Rig<\/strong> is a revolutionary machine designed for drilling roof-cutting holes above the belt conveyor in coal mines. It allows continuous belt operation while the rig straddles both sides of the conveyor, facilitating pre-splitting roof-cutting holes and installing anchor bolts or cables.<\/p>\n

Key Features of the Coal Mine Roof-Cutting Drill Rig<\/strong>:<\/h3>\n
    \n
  1. \n

    First-of-Its-Kind Design<\/strong>: Specifically engineered for roadways where roof-cutting holes are located above the conveyor, ensuring uninterrupted belt operation.<\/p>\n<\/li>\n

  2. \n

    High Hole Quality<\/strong>: Dual-boom roof support, hydraulic rod holders, and large-diameter high-strength drill rods ensure straight, high-quality boreholes compatible with directional blasting energy tubes.<\/p>\n<\/li>\n

  3. \n

    Precise Borehole Angles<\/strong>: Both drilling rigs have adjustable swing mechanisms along the coal mining area’s orientation and the roadway, ensuring through-cracks after directional blasting.<\/p>\n<\/li>\n

  4. \n

    Straight Line Boreholes<\/strong>: The lateral movement mechanism ensures boreholes are aligned in a straight line, cutting the roof along the pre-split seam without frequent travel unit adjustments.<\/p>\n<\/li>\n

  5. \n

    High Drilling Efficiency<\/strong>: Equipped with a 55 kW motor and 145 mL\/r variable displacement piston pump, the rig can operate independently or simultaneously, improving drilling efficiency.<\/p>\n<\/li>\n<\/ol>\n

    3. Meeting borehole angle requirements: Both drill booms are equipped with adjustment mechanisms for lateral swing angles along the orientation of the coal mining area. Both drilling rigs are equipped with parallel swing mechanisms for directional swing angles along the roadway’s orientation. This configuration effectively ensures that through-cracks are formed between boreholes after directional blasting.<\/li>\n
