Coal Mine Roof-Cutting Drill Rig

CMO2-400/55 (K) Coal Mine Roof-Cutting Drill Rig

  1. First of its kind at home and abroad: Designed for roadways where roof-cutting holes are located above the belt conveyor. It enables continuous belt operation while the rig straddles both sides of the conveyor to drill pre-splitting roof-cutting holes and install anchor bolts (cables) above the belt conveyor.
  2. High hole quality: Dual-boom roof support for stabilization, hydraulic holder for rod support, and large-diameter high-strength drill rods effectively ensure borehole quality, and the boreholes are straight and are compatible with directional blasting energy tubes.
  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.
  4. Boreholes aligned in a straight line: The lateral movement mechanism independently drives the drill boom, ensuring that all boreholes are aligned in a straight line. This allows the roof to be cut along the pre-split seam line, avoiding the need for frequent adjustments to the travel unit.
  5. High drilling efficiency: A 55 kW motor and a 145 mL/r variable displacement piston pump are equipped. This ensures that two drill rigs can operate independently or simultaneously, significantly improving drilling efficiency.

CMO2-400/55 (K) Coal Mine Roof-Cutting Drill Rig: High-Efficiency Pre-Splitting & Bolting

The Coal Mine Roof-Cutting Drill Rig 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.

Key Features of the Coal Mine Roof-Cutting Drill Rig:

  1. First-of-Its-Kind Design: Specifically engineered for roadways where roof-cutting holes are located above the conveyor, ensuring uninterrupted belt operation.

  2. High Hole Quality: 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.

  3. Precise Borehole Angles: Both drilling rigs have adjustable swing mechanisms along the coal mining area’s orientation and the roadway, ensuring through-cracks after directional blasting.

  4. Straight Line Boreholes: 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.

  5. High Drilling Efficiency: Equipped with a 55 kW motor and 145 mL/r variable displacement piston pump, the rig can operate independently or simultaneously, improving drilling efficiency.
