Flintknapping

A soft hammer is made of a piece of antler although bone and some very hard woods can be deer elk and caribou antler are all usable soft hammers Soft hammers are used when flaking very brittle material such as obsidian or when greater control is needed Soft hammers will not pass as much energy to the core and will absorb some of the force affording greater control of the

Hard rock cutting technologies for mining

Mechanical Hard Rock Mining Mechanisation of mining operations has been of interest for decades to improve productivity and reduce cost However in hard rock mining applications this has been impeded by the limitations of the existing mechanical rock fragmentation capabilities being constrained power limited strength of mechanical components and short cutter life.

Roadheader solutions in focus

Direct visual contact with the geology is also seen as an advantage for the steering process The Herrenknecht shaft boring roadheader SBR was developed specifically for mechanized sinking of blind shafts in soft to medium hard rock.

Rock bolts to support stabilize the unstable rock strata

Rock bolts have been used since many years to support and stabilize the unstable rock strata in mining and tunnel excavations They transfer load from the unstable rock exterior to the more stable rock interior A typical rock bolts consists of a plain or threaded steel rod with mechanical or chemical anchor at one end and a face plate nut
