OverView of THEORIES OF ROCK BOLTING Mining Science

In coal mining, the surrounding strata is weakened and fractured around mine openings in underground mines due to the in situ stress redistribution. The main purpose of rockbolt reinforcement is to improve the internal load bearing strength of the rock mass to support itself (Bieniawski, 1984). Rockbolt performance is influenced by the rockbolt type, anchorage system, strata lithology and
