Open-Pit Mining Down-the-Hole Drill Rig

The Open-Pit Mining Down-the-Hole Drill Rig is a crawler-mounted machine for blast-hole drilling in open-pit mines and quarries. Its pneumatic DTH hammer breaks rock at the bottom of the borehole, while the rotary head, feed system, and drill string advance the hole. Compressed air drives the hammer and removes cuttings. The drilling configuration is selected according to hole dimensions, rock conditions, bench layout, and production requirements.

DTH Drilling Performance
The hammer delivers impact energy close to the drill bit. Hammer size, bit diameter, drill pipe dimensions, and air supply are matched to the specified drilling range and ground conditions.

Integrated Air Supply
The compressor provides the pressure and airflow required for hammer operation and borehole cleaning. Matching these parameters to the selected hammer helps establish the required operating configuration.

Crawler Mobility
The tracked undercarriage supports movement between drilling positions on prepared mine benches. Travel speed, ground conditions, gradient, and turning space should be assessed during equipment selection.

Dry Dust Collection
The dry dust collection system captures drilling cuttings during operation. Filter arrangement, maintenance access, and site dust-control requirements form part of the configuration review.

Open-Pit Metal Mining
For production blast-hole drilling where the required hole diameter, depth, and drilling pattern match the selected DTH system.

Surface Coal Mining
For suitable surface drilling operations, subject to geological conditions, hole specifications, and site operating requirements.

Limestone Quarries
For production drilling supporting rock fragmentation and quarry extraction.

Bench and Pre-Splitting Drilling
For planned vertical or inclined holes when the feed geometry, positioning range, and working clearance meet the site drilling plan.

Drilling Tools
Specify hole diameter, required depth, hole inclination, and rock characteristics to determine the compatible hammer, bit, and drill pipe arrangement.

Compressor and Power
Confirm the required air pressure, airflow, and engine power against the selected hammer and expected operating conditions.

Dust Collection
Dust collection arrangements can be reviewed according to site requirements, drilling conditions, and available machine configurations.

Equipment Options
Customization can be assessed for compatible drilling tools, control arrangements, and other available equipment options. The final configuration is confirmed against the selected model and agreed technical requirements.

Define Hole Requirements
Provide the target diameter, effective drilling depth, inclination, and hole pattern. These details establish the basic drilling system requirements.

Assess Geological Conditions
Identify rock type, hardness, fracture characteristics, and expected water conditions. This information supports selection of the hammer, bit, and air supply.

Verify Site Access
Confirm bench width, ground slope, turning space, working clearance, and transport restrictions. Compare the machine dimensions and operating weight with site access and delivery arrangements.

Establish Production Targets
Provide the planned hole count, drilling metres per shift, and operating hours. These figures help assess configuration suitability for the required production schedule.

Assembly Inspection
Inspect key mechanical assemblies, feed components, rotating mechanisms, connections, and installed equipment against the approved machine configuration.

Functional Testing
Check engine startup, rotation, feed movement, hydraulic response, travel controls, and dust collection where fitted. Record the results according to the applicable inspection procedure.

Final Inspection
Verify model identification, agreed configuration, supplied accessories, machine condition, and shipment documents before dispatch. Inspection records should correspond to the machine being delivered.

Shipment Planning
Confirm operating weight, transport dimensions, loading arrangements, destination, and applicable import requirements before shipment planning.

Technical Documentation
The agreed document package can include the equipment specification, operating instructions, maintenance information, and a list of supplied components.

Spare Parts Support
Identify routine service items, drill bits, hammer consumables, and other relevant wear parts according to the selected configuration and expected operating conditions.
