An important anchoring element in construction work, rock bolts are used to stabilize rock excavations. They may be used singly or in arrays. They are also useful when it is necessary to prevent rockfall. For general-purpose applications, rock bolts are an important and much more economical alternative: because there is no need for cutting and threading operations, rock bolting can generate substantial savings in both time and labor costs.
