Показать описание
Raise Boring Method is one of the shaft construction techniques in rock where a tunnel or underground space has already constructed under the shaft and there is access to the bottom of shaft. The method starts with pilot drilling from the top and then reaming the shaft upward. In this video the reamer is connected and ready to start reaming upward. All excavated material can be removed from the lower level.
