Evaluation of cable bolt applications for Canadian underground mines
A market survey of all underground mines in Canada (Fig. 1) •
was completed to determine the extent to which cable bolts are being used as ground support. One hundred and nine questionnaires were distributed with 65% of them being returned completed. As a result, the quantity, types and locations of cable bolt installations have been determined. In addition, the grout pumps used, time required and cost of installations have been addressed. The popularity of other support types used in underground mines is summarized.
