Longwall face bolters

Sandvik DZ701 longwall face bolter

Our longwall face bolters enable a safe work method during longwall equipment recovery. Two powerful drilling rigs and accompanying control valves make both standard and cable bolting safe, easy and efficient.

Sandvik DZ701 is a longwall face bolter designed to stabilize the roof and face in a longwall coal mine before equipment recovery operations. The bolter is powered by the longwall hydraulic system and operates on the AFC rack. Two independent, hydraulically controlled drill rigs offer proven safety and efficiency for bolting operations.
