One-hole automation is designed for drilling a single long hole automatically in any direction to predefined depth, including coupling and uncoupling of rods.
It eases the work of the operator and increases productivity, by making the drilling process more controllable. It also allows the drilling operation to continue through shift change and breaks, therefore increasing the operational efficiency in long hole drilling.
The operator can use the following operating modes in one-hole automation:
• Drill – rods are automatically added, hole is drilled to given depth and rods are left in the hole
• Drill and uncouple – in addition to the “Drill” mode features, uncouples the rods
• Uncouple – the feature only uncouples the rods
The following features are designed for improving hole quality: extra flushing sequences during the drilling cycle, break through tolerance and rushing detection.
Information on the progress of drilling is shown in the operator display. User friendly and comprehensive diagnostics system helps in fault finding and the status of CAN modules and sensors can be easily checked.
One Hole Automation Upgrade Solution includes TMS DDS instrumentation and Rod Handler Sequence Control, if these options are not yet installed on the machine.
The use of rock drill power extractor is recommended in combination with One-hole automation, for the ease of uncoupling rods and for improved productivity (Upgrade Solution available).
