Kaishan underground rock bolting rigs are hydraulic drill jumbos purpose-built for roof and wall anchor support in underground headings. The KM Series (KM211, KM311) positions drill feed angles for systematic rock bolting patterns, keeping crews under supported ground while installation cycles stay fast. A dedicated bolting machine improves both safety and cycle time compared to adapting a face drill. At publication, the series covers 2 models — key specifications are listed below.
| Model | Machine | Hole diameter (mm) | Weight (kg) |
|---|---|---|---|
| KM211 → | KM211 Underground Bolting Drill Rig | 32–51 mm | 12000 kg |
| KM311 → | KM311 Hydraulic Rock Bolting Rig | 32–51 mm | 12000 kg |
