Process Of Using A Mining Roadheader To Excavate An 800Meters Water-Conveying Tunnel !

A Little Wisdom Helps You Become Smarter !

The following is the general construction method for excavating an 800-meter water-conveying tunnel using a mining roadheader :

Construction Preparation

– Conduct geological exploration.
Select a suitable roadheader based on rock types, hardness, and groundwater conditions. Prepare the construction site with stable power supply and good drainage. Debug the roadheader !

Tunneling Construction

– Start tunneling from the entrance.
Control the cutting head’s speed according to rock hardness. Transport slag out. Use laser pointer to control direction. Perform support after tunneling a certain distance !

Waterproofing And Drainage

– Ensure the roadheader’s waterproofing. Use waterproof materials for tunnel lining. Set up drainage grooves and pumps !

Through Construction

– Slow down and control direction when approaching the end. Detect remaining rock thickness. Inspect and repair after through. Finish lining and waterproofing !
