Rapid Tunneling and Bolting Integrated System

EJM340/4-2 Rapid Tunneling and Bolting Integrated System

  1. The main unit has a cutting power of 340 kW, providing strong power, high cutting capability, and efficiency.
  2. Simultaneous tunneling and bolting operations significantly enhance work efficiency, achieving rapid tunneling.
  3. With a low ground pressure of 0.16 MPa, the crawler remains stationary during tunneling, maximizing protection of the roadway floor and adapting to broken floor roadway tunneling.
  4. The hydraulic system is configured with a high margin, ensuring the longevity of hydraulic components and supporting simultaneous operation of all bolting machines.
  5. An integrated dust removal system is equipped, including water mist dust removal, foam dust removal, and wet/dry dust removal, to improve dust removal efficiency and ensure a safe working environment in the roadway.
  6. The machine operates with a small unsupported roof span, making it suitable for poor roof conditions.
  7. The cutting advance is driven by a cylinder, keeping the machine body stationary during cutting to minimize crawler-induced floor damage and enable adaptation to poor floor conditions.
  8. It has advanced drilling and drainage functions for water, gas, and geological exploration.
