Bolt and away we go

摘要

Many technical initiatives employed in mining are actually derived from civil engineering. Such initiatives and their subsequent development and refinement are then further "fermented and distilled" to a point where they also become an acceptable and accepted mining method. Whilst surface bolting was first documented as being used to retain side-walls in civil engineering works, it is debatable whether its migration underground was necessitated by more complicated subterranean engineering work or whether mining simply adopted the technique for underground bolting as its own.
