Mining machine with improved rib reach capability and method of use thereof |
摘要 |
An apparatus is for use by an operator in forming boreholes in a mine passage including a rib and a roof. The apparatus includes a boom having a proximal end mounted to a base, such as a vehicle. A drill supported by the boom near a distal end thereof is adapted for drilling into the rib of the mine passage. An operator's station carried by the boom adjacent the drill includes a platform for supporting the operator arranged at least partially between a generally vertical plane aligned with the second lateral side and the rib. Accordingly, the operator can access the rib when positioned on the operator's station without interference from the boom.
