Hydraulic Roof Bolter Drilling Vehicle for Coal Mines

The hydraulic roof bolter drilling vehicle for coal mines is a highly efficient support equipment specially designed for excavation faces in underground coal roadways and semi-coal rock tunnels. It not only enables simultaneous installation of roof and sidewall bolts and cables, but is also capable of drilling blast holes, probe holes, water exploration holes, and gas exploration holes in coal and rock formations with hardness ranging from f=3 to 10. It is suitable for support heights from 3 to 6 meters, widths from 4.4 to 6 meters, and can adapt to roadway gradients of up to ±16°, fully meeting the diverse needs under complex geological conditions in coal mines.

Main Features of the Hydraulic Roof Bolter Drilling Vehicle

• Utilizes an advanced full-hydraulic system with automatic pump flow adjustment, and is equipped with ergonomically designed hydraulic pilot handles for flexible and effortless operation.
• The left and right drilling arms and boring mechanisms are interlocked, and the support leg cylinders and support sections can be locked at any time, ensuring safety in underground operations and significantly reducing energy consumption.
• Dual drilling arms and propulsion systems can work independently or in coordination, greatly improving construction efficiency.
• The propulsion mechanism allows for multi-position movement and multi-angle rotation, making it flexible for various tasks such as roof and sidewall bolt and cable installation, face work, blast hole drilling, and probe hole drilling.
• The front support structure provides advanced support, offering enhanced safety for operators.
• The whole drilling arm can rise and fall with the platform, adapting to different roadway cross-sections and improving operational convenience.
• The pedal design allows for flipping and lateral rotation, easily accommodating different roadway widths and enhancing construction flexibility.
• The built-in booster system can directly drive tensioning equipment, enabling on-site cable tensioning without the need for additional devices.

Application Fields

The hydraulic roof bolter drilling vehicle is widely used for bolt and cable support operations in coal mine roadways and semi-coal rock excavation faces, as well as for drilling blast holes, probe holes, water exploration holes, and gas exploration holes. It is especially suitable for underground workplaces with limited space, high support requirements, and complex and variable geological environments.

Operating Conditions

• Suitable for altitudes not exceeding 2000 meters.
• Operating temperature range: -5℃ to +40℃.
• Relative air humidity not greater than 95% at 25℃.
• Safe for use in mines containing explosive gases such as methane.
• Applicable in environments without destructive insulating gases or vapors.
• Not suitable for locations with long-term continuous dripping water.
