| An extensive study was conducted to determine the effects of rock mass parameters and operational parameters on the performance of Swellex rock bolts, wherein pull test data was compiled from various mines in North America and Europe. The data was statistically analysed, and the results, which quantify the influence of various factors on the performance of the Swellex bolt, were evaluated. A set of recommendations was formulated in order to assist in the practical design and efficient use of Swellex bolts.;Little pull test data existed concerning Swellex bolts, and the information available was non-standardized. Therefore, a form was developed to assist in the standardization of the pull test information that is recorded and a database was created to house pull test data. The form and database will be widely available for use by mining engineers. In time, the database will become and invaluable tool in the design of rock bolt support. |
