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. The global Roof Bolters market was ...
The roof bolters still have to climb through the middle of the machine to set the ATRS and perform their primary duties. The position controls are operated from the mid-point of the machine. The drilling capacity remains the same, but safety and productivity improves from a materials handling aspect while bolting the rib.
The jig enrichment technology can also be used in the processing of other mineral resources, espe-cially in removing of impurities at initial stages of aggregates, sand or gravel treatment [11]. It is also possible to recover in jigs building materials from demolition debris and road materials [12], electronic waste or plastic [13,14].
