The solution that everyone has been driving towards is a true simultaneous cut-and-bolt machine for gateroad development. the machine required is one that can bolt close to the face and ideally handle dense bolting patterns for both the roof and ribs, as well as maintaining a high reliability, while continuing to meet the roadway development requirements.
