Abstract
A long-recognized goal in high-speed tunneling and mining has been the development of a continuous drill and blast excavation capability. This report presents the results of tests conducted on an integrated drill-load-shoot system in which the explosive and initiator are loaded directly through the drill steel as the latter is withdrawn from the hole.
