Reducing Control Selection Errors Associated with Underground Bolting Equipment

The aims of the research were to determine whether arbitrary shape coding was effective in reducing selection error rates and whether any advantages exist for mirror or place layouts for dual control situations.

Selecting the incorrect control during the operation of underground bolting and drilling equipment causes serious injuries. Shape coding and the layout of dual control banks are two aspects of control design which require further examination. The aims of this research were: (i) to determine whether arbitrary shape coding was effective in reducing selection error rates in a virtual analogy of roof-bolting; and (ii) to determine whether any advantages exist for mirror or place layouts for dual control situations in this situation.
