A roof bolter is a hydraulically driven miner-mounted bolting rig used to install rock bolts in mines, tunnels, underground power plants, and storage facilities.

Roof bolting is also a common application in underground coal mines for securing mine roofs to be self-supportive. It is extremely dangerous as an occupation, accounting for nearly 56 percent of injuries in underground coal mining operations.^[1] According to U.S. law, all underground coal mine entries must be roof bolted.
